Slow-crystallising polyarylene sulphide with high melt viscosity - obtd. by melting mixt. of polyarylene sulphide, heterocyclic sulphonic acid or heterocyclic nitro cpd., and opt. glass fibre etc.

摘要

Arylene sulphide polymers (I) are claimed; (I) are produced by melting a mixt. of (A) 70-99.9 wt.% polyarylene sulphide, (B) 0.1-30 wt.% heterocyclic cpds. substd. with at least one sulphonic acid gp. or sulphonic acid deriv. and/or at least one nitro gp., and (C) 0-400 pts. wt. glass fibre and/or other fillers and reinforcing materials (w.r.t. 100 pts. wt. A + B). Pref., (A) is PPS, (B) are known cpds., e.g. quinoline 8-sulphonic acid (II), 5-nitro-1H-triazole, 8-hydroxyquinoline 5-sulphonic acid, 2-methyl-6-nitrobenzthiazole, etc. (31 examples given); (B) are incorporated in the melt (at up to 400 deg.C), e.g. in an extruder.
