Title:
PROPYLENE-ETHYLENE-DIENE TERPOLYMER POLYOLEFIN ADDITIVES FOR IMPROVED TIRE TREAD PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2019/226843
Kind Code:
A8
Abstract:
Elastomeric compositions comprising propylene-ethylene-diene terpolymer based polyolefin additives useful in tire tread compositions. The elastomeric compositions comprise 100 phr (parts by weight per hundred parts of total elastomer) diene elastomers; about 0 to about 80 phr of processing oil; 0 to about 80 phr of a hydrocarbon resin; about 60 to about 140 phr of filler; a curative agent; and about 5 to about 30 phr of a silane functionalized propylene- ethylene-diene terpolymer. The silane functionalized propylene-ethylene-diene terpolymer comprises from about 2 wt.% to about 40 wt.% of ethylene and/or C4-C20 α-olefins derived units, from 0.5 to 10 wt % of diene derived units, and a silane coupling agent. The present elastomeric compositions are useful as tire tread compositions for improved tire performance.
