Abstract:
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 150Â° 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 &mgr;mol/g per the total weight of the fluorine-containing polymer, and represented by the formula (1):A1â€”(X)â€”(Y)â€”A2â€ƒâ€ƒ(1) wherein X is a structural unit of the formula â€”(CH2CX1X2)â€” (wherein X1 and X2 are the same or different, and each is hydrogen atom, fluorine atom, â€”(HCH2)pâ€”(O)qâ€”Râ€”B1 (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, B1 is hydrogen atom, fluorine atom, hydroxy group or epoxy group, p is 0 or 1 and q is 0 or 1), â€”COâ€”Râ€”B1 (R and B1 are the same as above) or â€”COOâ€”Râ€”B1 (R and B1 are the same as above));Y is a structural unit of the formula â€”(CF2CY1Y2)â€” (wherein Y1 and Y2 are the same or different, and each is hydrogen atom, fluorine atom, chlorine atom, â€”(CF2)râ€”(O)sâ€”Rf)tâ€”(CH2)uâ€”B2 (Rf is a dihydric fluorine-substituted organic group having carbon atoms of 1 to 14, B2 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(CF2)vâ€”B3 (B3 is hydrogen atom, fluorine atom or chlorine atom, and v is an integer of 1 to 10)); both A1 and A2 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 CH2&boxH;CHF, CH2&boxH;CF2 or fluoroalkyl-&agr;-substituted acrylate (substituent is hydrogen atom, fluorine atom or methyl); X may not be present when Y has the structural unit derived from CH2&boxH;CF2 or CH2&boxH;CHCl; at least one of A1 and A2 contains hydroxy group, epoxy group or glycidyl group when both of X and Y do not contain hydroxy group, epoxy group or glycidyl group, wherein the heat resistive thermoplastic resin (b) is at least one member selected from the group consisting of aromatic polyesters, polyamide imides, polyarylene sulfides, polyketones, polyether nitrites, polycarbonates, polyphenylene ethers, polysulfones, polyether sulfones, polyether imides and polyimides.
