Polyamide contg. mono:alkenyl-arene conjugated diene block copolymer - and having increased resilience and reduced elasticity modulus

摘要

Compsn. comprises a mixt. of a polyamide (I) and 8-30 pts.wt. (per 100 pts. mixt.) of a monoalkenyl arene/conjugated diene block copolymer (II). Use of (II) gives a compsn. having increased resilience and reduced modulus of elasticity without affecting the other props. of (I). Used for producing mouldings by injection or extrusion. (I) is pref. polyhexamethylene adipamide or polycaprolactam. (II) is pref. a triblock butadiene styrene thermoplastic elastomer of the type SSS-BBBB-SSS.
