[0043] [resin (S)]
[0044] The resin (S) contained in the resin composition of the first embodiment of the present invention contains a functional group-modified polyarylether (A) and a thermoplastic resin (B).
[0045]
[0046] The functional group-modified polyarylether (A) contained in the resin composition of the first embodiment can be obtained by reacting a polyarylether described below with a modifier described below.
[0047] The polyarylether used as a raw material of the functional group-modified polyarylether (A) contained in the resin composition of the first embodiment is not particularly limited.
[0048]Examples of polyarylethers include poly(2,3-dimethyl-6-ethyl-1,4-phenylene ether), poly(2-methyl-6-chloromethyl-1,4 -phenylene ether), poly(2-methyl-6-hydroxyethyl-1,4-phenylene ether), poly(2-methyl-6-n-butyl-1,4-phenylene ether), poly(2-ethyl-6-isopropyl-1,4-phenylene ether), poly(2-ethyl-6-n-propyl-1,4-phenylene ether), poly (2,3,6-trimethyl-1,4-phenylen...
no. 2 approach
[0097] A second embodiment of the present invention relates to a method for producing a resin molded body, and a molded body and a laminate obtained by the production method. In the second embodiment, one of the features is that polyarylene ether not modified by functional groups, carbon fiber, and thermoplastic resin are used as the molding material. Specifically, it is characterized in that it includes a step of producing a carbon member including a polyarylether not modified by a functional group and carbon fibers, and a step of adding a thermoplastic resin to the carbon member.
[0098]
[0099]In the present embodiment, examples of polyarylene ethers not modified by functional groups contained in carbon members (hereinafter, sometimes simply referred to as “unmodified polyarylene ethers”) include functional group-modified polyarylene ethers. The raw material of the ether (A) is the substance described in detail in the first embodiment. Among them, as in the first embod...

[0171] 100 parts by mass of polyarylether [BLUESTAR NEW CHEMICAL MATERIALS Co.LTD.: LXR040; poly(2,6-dimethyl-1,4-phenylene ether)], radical generator (NOFMER: NOFMER) BC90; 4 parts by mass of 2,3-dimethyl-2,3-diphenylbutane) and 1 part by mass of a modifier (fumaric acid) were dry-blended, and kneaded using a twin-screw with a cylinder diameter of 32 mm A machine (manufactured by Coperion: ZSK32MC) was used to perform melt kneading at a screw speed of 200 rpm and a set temperature of 300°C. The resin temperature at this time was about 330°C.
[0172] After the strands are cooled, they are pelletized to obtain fumaric acid-modified polyarylethers. In order to measure the degree of modification (modification amount), the modification amount was obtained as the acid content from the neutralization titer measured in accordance with JIS K 0070-1992. The modification amount was 1.60% by mass.
