Abstract:
A thermoplastic resin composition which comprises a blend obtained by blending 0.1 to 99% by weight of (a) a fluorine-containing polymer having a functional group and a number-average molecular weight of 2000 to 1000000 and 1 to 99.9% by weight of (b) a heat resisting polyarylene sulfide resin having a crystalline melting point or glass transition temperature of not less than 150.degree. C.; said fluorine-containing polymer (a) having a functional group that is at least one selected from fluorine-containing polymers having functional groups, in which a concentration of the functional groups at a main chain end portion and side chain portion is 2 to 2000 .mu.mol/g per the total weight of the fluorine-containing polymer, and represented by the formula (I): ##STR6## wherein X is a structural unit of the formula --(CH.sub.2 CX.sup.1 X.sup.2)-- (wherein X.sup.1 and X.sup.2 are the same or different, and each is hydrogen atom, fluorine atom, --(CH.sub.2).sub.p --(O).sub.q --R--B.sup.1 (R is a dihydric hydrocarbon group having carbon atoms of 1 to 20 or dihydric fluorine-substituted organic group having carbon atoms of 1 to 20, B.sup.1 is hydrogen atom, fluorine atom, hydroxy group or epoxy group, p is 0 or 1 and q is 0 or 1), --OCO--R--B.sup.1 (R and B.sup.1 are the same as above) or --COO--R--B.sup.1 (R and B.sup.1 are the same as above));Y is a structural unit of the formula --(CF.sub.2 CY.sup.1 Y.sup.2)--(wherein Y.sup.1 and Y.sup.2 are the same or different, and each is hydrogen atom, fluorine atom, chlorine atom, --(CF.sub.2).sub.r --(O).sub.s --(R.sub.f).sub.t --(CH.sub.2).sub.u --B.sup.2 (R.sub.f is a dihydric fluorine-substituted organic group having carbon atoms of 1 to 14, B.sup.2 is hydrogen atom, halogen atom, hydroxy group, epoxy group or glycidyloxy group, r is 0 or 1, s is 0 or 1, t is 0 or 1, and u is an integer of 1 to 3) or S(CF.sub.2).sub.v --B.sup.3 (B.sup.3 is hydrogen atom, fluorine atom or chlorine atom, and v is an integer of 1 to 10));both A.sup.1 and A.sup.2 are end portions of a main chain;provided that each of X and Y may comprise two or more structural units;Y may not be present when X has the structural unit derived from CH.sub.2 .dbd.CHF, CH.sub.2 .dbd.CF.sub.2 or fluoroalkyl-.alpha.-substituted acrylate (substituent is hydrogen atom, fluorine atom or methyl);X may not be present when Y has the structural unit derived from CH.sub.2 .dbd.CF.sub.2 or CH.sub.2 .dbd.CHCl;at least one of A.sup.1 and A.sup.2 contains hydroxy group, epoxy group or glycidyl group when both of X and Y do not contain hydroxy group, epoxy group or glycidyl group; said resin composition contains only the fluorine-containing polymer represented by the formula (I) as the fluorine-containing polymer having functional group.
