Thermoplastic resin composition

Abstract

A thermoplastic resin composition comprising: (A) 1-99 parts by weight of polymethacrylimide and (B) 99-1 parts by weight of ethylene-ethyl acrylate copolymer, polyamide-imide, polyether-ether ketone, or polyether sulfone. The thermoplastic resin composition has a high impact strength as well as good processability.

We claim: 
     
       1. A thermoplastic resin composition which comprises: (A) 1-99 parts by weight of a polymer containing at least 10% by weight of methacrylimide units represented by the formula (I) below: ##STR2##  (wherein R denotes a hydrogen atom or a C 1  -C 20  hydrocarbon selected from the group consisting of aliphatic, aromatic or alicyclic hydrocarbons) and polymer by-products having functional groups selected from the group consisting of acid functional groups, acid anhydride functional groups, and mixtures thereof wherein the acid functional groups and acid anhydride functional groups in the polymer by-product are more than 0.4 milliequivalents for the polymer, and   (B) 99-1 parts by weight of at least one kind of thermoplastic resin selected from the group consisting of styrene-maleimide copolymer, polyphenylene ether-polystyrene blend polymer, polyaryl ester (all aromatic polyester), and polyether imide (with the total amount of (A) and (B) being 100 parts by weight).
