    摘要: A readily crystallizable arylenesulfide resin composition is produced by adding, to 100 parts by weight of an arylenesulfide polymer, 0.01 to 10.0 parts of an organic acid or organic acid anhydride having a high boiling or melting point such as 2,6-naphthalene dicarboxylic acid, and then heating the mixture to a temperature not lower than the melting point of the polymer. The resulting resin composition is characterized in that its crystallization from its glass state and molten state is very rapid, in that it forms very fine spherulite structures, and in that it has a high degree of crystallization, a very crystallizable character, and other desirable characteristics.

    摘要: Disclosed herein is a composition of polyarylene thioether prepared by combining 0.001 to 10 parts by weight of kaoline of the mean particle diameter of 0.03 to 2 .mu.m with 100 parts by weight of polyarylene thioether having the repeating unit of ##STR1## as the main constituent. The composition of polyarylene thioether has a high crystallization rate and forms a minute spherulite structure. Moreover, the composition having a short molding cycle at the time of melt molding, generates a small amount of the flash and gives the molded products excellent in mechanical properties.Disclosed herein also is a composition prepared by further combining an inorganic filler and/or a fibrous filler with the above-mentioned composition of polyarylene thioether.
