Blends of polyarylene sulphide(s) with polyolefin(s) and Schiffs bases contg. nitro gps. - suitable for injection moulding and have improved toughness and elongation at failure

摘要

Polymer blends comprise (A) 50-99.4 wt.% polyarylenesulphide, pref. polyphenylenesulphide, (B) 0.5-50 wt.% polyolefins, (C) 0.1-5 wt.% of nitro gp.-contg. Schiff's bases contg. 8-22C alkyl gps. and have the formula (NO2)n-Ar1-CR1=N-R2 (I) and/or (NO2)n-Ar1-CR1=N-Ar2-R2 (II) in which R1 = H, 1-22C alkyl or 6-14C aryl, R2 - 8-22C alkyl, Ar1 = 6-14C aromatic residue, Ar2 = 6-14C arylene residue and n = 1 or 2, esp. 1, and (D) 0-300 pts. wt. (per 100 pts. wt. A+B+C) of conventional fillers and/or reinforcing agents and/or carbon black. USE/ADVANTAGE - The blends are suitable for injection moulding and give moulded bodies with improved mechanical properties esp. improved toughness and elongation at failu
