International Classification:

C08L 7/00
B60C 1/00

Abstract:

An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): 0 to about 50 phr of a polybutadiene having a cis-1,4 linkage content of at least 95%; about 50 to 100 phr of natural rubber or polyisoprene; a curative agent; an antioxidant; about 10 to about 80 phr carbon black; optionally about 30 to about 70 phr silica; about 1 to about 20 phr hydrocarbon resin; and about 5 to about 30 phr of a polymer selected from the group consisting of ethylene-propylene-diene terpolymer, butyl rubber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methyl-styrene-co-isoprene) terpolymer. The polymer based on ethylene-propylene-diene terpolymer, butyl rubber, oly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer may be functionalized.

Abstract:

An elastomeric composition is disclosed. The elastomeric composition includes, per 100 parts by weight of rubber (phr): about 5 to about 40 phr of styrene/butadiene copolymer; about 60 to about 100 phr of natural mbber or polyisoprene; a curative agent; an antioxidant; about 1 to about 20 phr carbon black; about 5 to about 40 phr plasticizing agent; about 40 to about 80 phr silica; about 1 to about 20 phr silane coupling agent and about 5 to about 30 phr of a polymer selected from the group consisting of ethyl-ene-propylene-diene terpolymer, butyl mbber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer. The polymer based on ethylene-propylene-diene terpolymer, butyl mbber, poly(isobutylene-co-para-methylstyrene) and poly(isobutylene-co-para-methylstyrene-co-isoprene) terpolymer may be functionalized.

International Classification:

C08J 3/22
C08K 3/06
C08K 5/00

Abstract:

This invention relates to sulfur, vulcanization accelerator and carbon black master batch formulations comprising either a semi-crystalline propylene-olefin copolymer or a combination of a semi-crystalline propylene-olefin copolymer and a hydrocarbon resin. The semi-crystalline propylene-olefin copolymer or the combination of semi-crystalline propylene-olefin copolymer and hydrocarbon resin imparts a high hardness property to the carbon black, sulfur and accelerator master batch formulations thereby preventing pellet agglomeration during storage and allowing for ease in material handling.
