High temp. dimensionally stable reinforced polyolefin compsns. - comprising norbornene-ethylene! copolymer(s) and pref. glass fibres or asbestos

摘要

Reinforced polyolefins with high temp. dimensional stability, reduced water absorption and good dielectric properties mixts. contg. these copolymers and 10-50 wt % inorganic reinforcing agents. The compsns. also contain stabilisers and opt. lubricants. The reinforcing agent as pref glass fibres or asbestos. The compsns pref. also contain an elastomer.
