Abstract

A thermoplastic resin composition comprising a blend obtainable by blending 0.1 to 99% by weight of (a) a fluorine-containing polymer having a number-average molecular weight of 2000 to 1000000 and having hydroxy group or epoxy group at least at one of end portions of a main chain and side chain of the polymer, and 1 to 99.9% by weight of (b) a heat resisting thermoplastic resin having a crystalline melting point or glass transition temperature of not less than 150° C. The present invention can provide a composition comprising various heat resisting thermoplastic resins and a fluorine-containing polymer having a functional group which is capable of developing an affinity with said resins and forming a uniform dispersion

Claims

1. A method of improving affinity in resin compositions of a heat resistive thermoplastic resin (b) having a crystalline melting point or glass transition temperature of not less than 150°

C., which comprises blending the heat resistive thermoplastic resin (b) with a fluorine-containing polymer (a) having a functional group and a number-average molecular weight of 2000 to 1000000;

said fluorine-containing polymer (a) having the functional group is at least one selected from fluorine-containing polymers having functional groups, in which a concentration of the functional group at a main chain end portion and side chain portion is 2 to 2000 μ

mol/g per the total weight of the fluorine-containing polymer, and represented by the formula (1);
