ABSTRACT:
The present invention relates to a poly(cyanoarylether)based resin composition comprising 100 parts by weight of poly(cyanoarylether) having a repeating unit represented by the formula: ##STR1## (wherein Ar is ##STR2## as a main constitutional component and 0.01 to 3 parts by weight of at least one crystallization nucleating agent selected from the group consisting of talc, mica and carbon black each having a particle diameter of not more than 3 .mu.m.
In the composition of the present invention, the rate of crystallization of poly(cyanoarylether) is greatly improved. Thus, the productivity of molding can be increased. Furthermore, the composition of the present invention can provide moldings having excellent heat resistance without annealing.
