Polyarylene sulfide, a process for the preparation thereof and a composition comprising the same

摘要

A polyarylene sulfide in which a ratio of terminal -SX groups to a total of the terminal -SX groups and -SZn-groups is less than 20 mole %, wherein X represents an alkali metal or a hydrogen atom, and which has a melt viscosity, V6 of 100 to 2,000 poises. Also disclosed are a composition comprising 100 parts of the above polyarylene sulfide, 0.01 to 20 parts of zeolite and 0.01 to 20 part of silica, and a process for the preparation of the above polyarylene sulfide.
