Co-granule extrusion of a polyolefin with rubbers prevents - agglomeration

摘要

extrusion of a polyolefin with rubbers prevents agglomeration 100 pts. of a satd. ethylene/propylene or unsatd. EPDM amorphous rubber is extrusion granulated with 1-30 pts. of a crystalline homo or copoly (alpha monoolefin) pref. polyethylene or polypropylene. Incorporation of polyolefin reduces superficial adherence of granules without affecting desirable properties of the rubber.
