PAS REDUCED IN FORMATION OF FLASH AND SHOWING HIGH UV STABILITY AND GOOD MECHANICAL PROPERTY

摘要

PURPOSE: To obtain a PAS blend wherein good mechanical properties, satisfactory UV stability and proper flowability are combined with the min. formation of flash. ;CONSTITUTION: A mixture onsists of 99.8-70 wt.% of a polyarylene sulfide (A), 0.2-30 wt.% of a novolac like condensate (B) obtained by the acid catalystic condensation of a phenolic compd. (B1) and a nitroaryl keto compd. (B2) and 0-400 wt.%, based on the total amt. of (A+B), of a reinforcing material or filler (C).;COPYRIGHT: (C)1993,JPO
