Title:
GRAFTED MALEIMIDE-STYRENE-G-POLYPROPYLENE COPOLYMERS FOR IMPROVING HYSTERESIS IN RUBBER COMPOUND
Document Type and Number:
Japanese Patent JPH11335492
Kind Code:
A
Abstract:

To obtain a blend of high-damping copolymer having excellent tensile strength, tear strength, maximum elongation and damping characteristics, useful for automobile parts, precision apparatuses, etc., by using a specific polyalkylene grafted centipede type nitrogen-containing polymer.

This blend is obtained by mixing (A) a polyalkylene grafted poly (alkenylbenzene-comaleimide) copolymer containing 50-99 wt.% of a poly(alkenylbenzene-comaleimide) contributed monomer unit and l-50 wt.% of a maleated polyalkylene contributed monomer unit with (B) an elastomer (co)polymer. The component A is obtained, for example, by reacting a maleated polypropylene and a poly (alkenylbenzene-comaleimide) with a diamine.
