Polyarylene sulfide and a composition thereof
First Claim
1. A composition comprising 100 parts by weight of (A) a polyarylene sulfide and 0.01 to 5.0 parts by weight of (B) at least one silane compound, characterized in that the polyarylene sulfide comprises methylene chloride extractable components in an amount of not more than 0.7% by weight, has a melt viscosity, V6, of 20 to 15,000 poises and a content of --SX groups of at least 15 micro moles/g, wherein X represents an alkali metal or a hydrogen atom, the silane compound being selected from the group consisting of methacryloxy silane compounds, ureido silane compounds and epoxy silane compounds.

Abstract
Polyarylene sulfide (PAS) is disclosed, of which extract with methylene chloride is in an amount of not more than 0.7% by weight, a melt viscosity V6 is 20 to 15,000 poises and a content of --SX groups is at least 15 micro moles/g, wherein X represents an alkali metal or a hydrogen atom. The PAS is prepared as follows: an alkali metal sulfide is reacted with a dihaloaromatic compound in an organic amide solvent, while a part of a gaseous phase in a reactor is condensed by cooling a gaseous phase part of the reactor to return the condensed liquid to a liquid phase; and the polyarylene sulfide thus prepared is washed with an organic solvent and then with water. The present invention also provides a composition comprising 100 parts by weight of (A) the aforesaid PAS and 0.01 to 5.0 parts by weight of (B) at least a silane compound selected from the group consisting of methacryloxysilane compounds, ureidosilane compounds and epoxy silane compounds.
