DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Drawings
The drawings are objected to because the single drawing is not labelled. “Where only a single view is used in an application to illustrate the claimed invention, it must not be numbered and the abbreviation "FIG." must not appear.” (37 CFR 1.84(u)(1).) The appropriate designation is “FIGURE” or “Figure.” Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Objections
Claim 1 is objected to because of the following informalities:
Claim 1, line 9, line 31-32, and line 47 recites “thermometer, a water separator, and a nitrogen gas fed,”. The claim should instead read “thermometer, a water separator, and a nitrogen gas feed,”.
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-7 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.

which causes confusion. Typically, arrows indicate a chemical reaction. However, the figure is not a chemical reaction. Is R represented by the group on the right? Furthermore, is R the same as the R in the structure shown below?

The examiner invites the applicant to clarify. For purposes of examination, R is interpreted as representing the structure to the right of the arrow and is the same R as the figure above.
Claim 1, page 3, line 20, claim 5, lines 5-7, recites “phr” which causes confusion. Phr can be defined as parts per hundred rubber or parts per hundred resin. Which one does the applicant intend? For purposes of examination, phr is interpreted as parts per hundred resin.
Claim 7 recites the limitation “the low-molecular-weight acrylic copolymer” in line 3. There is insufficient antecedent basis for this limitation in the claim.
Claims 2-7 are rejected for being dependent on claim 1.

then raising the temperature to 175-190° C, and continuously reacting for 2.5-3.5 h; and after a high-temperature polymerization reaction is completed, cooling a reaction system to a room temperature, adding 4-vinylbenzyl chloride and stirring at the room temperature for 20-25 h until the reaction is completed,
pouring a reaction product into deionized water,
crushing the product after being cooled, filtering after being washed with ethanol and deionized water, and then drying with blast air at 60° C for 4-8 h, and
vacuum-drying at 55-65° C for 16-20 h;

Claim Interpretation
In claim 1, the recitation of “the value range of m being 1-40% and the value range of n being 60-99%” is interpreted as based on the chain segment total length m+n in view of the instant specification page 6.
Allowable Subject Matter
Claims 1-7 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
The following is a statement of reasons for the indication of allowable subject matter:
Claims 1-7 are allowed over the closest prior arts, Fan (EP 0106023 A2 as listed on IDS dated June 16, 2023) and Cao et al. (US 20050282919).
Fan teaches an end capped polyaryletherketone having the formula Z (̵ polyarylene polyether chain Z' wherein Z and Z' are each a monovalent unsaturated organo moiety, the polyarylene polyether chain being substituted or unsubstituted (claim 1). Fan teaches in Example 47, a polymer formed from 4,4’difluorobenzophenone and hexafluorobisphenol-A (structure shown below) (page 131, line 19-35). Fan teaches the polymer is end-capped with vinyl benzyl groups via the potassium phenolate end groups using vinyl benzyl chloride.

Fan does not teach or fairly suggest a preparation method for a coating material comprising the specific steps of S1: forming a high temperature self- crosslinking fluorine-containing polyaryletherketone containing two crosslinking groups of styrene group and thioether group as recited in the instant claim, S2: forming a high-temperature self-crosslinking fluorine-containing polyaryletherketone containing styrene group as recited in the instant claim, S3: forming a high-temperature self-crosslinking fluorine-containing polyaryletherketone containing thioether group as recited in the instant claim, and S4: preparing a coating material by dissolving a high-temperature self-crosslinking material, wherein high-temperature self-crosslinking fluorine-containing polyaryletherketone comprising one or more of the high-temperature self-crosslinking fluorine-containing polyaryletherketone containing two crosslinking groups of the styrene group and the thioether group, the high-temperature self-crosslinking fluorine-containing polyaryletherketone containing the styrene group, and the high-temperature self-crosslinking fluorine-containing polyaryletherketone containing the thioether group, and adding a diluent, a flatting agent, and a lubricant as recited in the instant claims.
Cao et al. teach an oligomer synthesized using 4,4’-difluorobenzophenone, 4,4’-(hexafluoroisopropylidene)diphenol, and anhydrous potassium carbonate in a mixture of 220 mL of DMSO and 110 mL of toluene, mixed slowly under a nitrogen stream, heating at ~120°C for 1 hour and raised to ~140°C for 2 hours, and then finally heating to 160°C for 3 hours. After cooling to ~70°C with continue stirring, the precipitates were filtrated and washed with distilled water 4 times and dried at 80°C overnight and then dried under vacuum for 2 days. The oligomer has the following structure:
