US Classification:

524515, 524519, 524567, 524578, 152525

Abstract:

Transparent and colorable elastomeric compositions are provided. The transparent elastomeric compositions can be covulcanized with rubbers such as polybutadiene, polyisoprene, styrene-butadiene rubber, styrene-isoprene-butadiene rubber, isoprene-butadiene rubber, ethylene-propylene diene rubber or natural rubber and a processing aid. The colorable rubber compositions have sufficient properties to function as a reinforcing member in a shoe sole or automobile tire.

Abstract:

The present invention includes elastomeric compositions of BIMS elastomers suitable for abrasion resistant, high traction and/or barrier articles. The compositions and articles made from those compositions of the inventions can be described in any number of embodiments. In one embodiment, the composition suitable for an abrasion resistant article includes from 5 to 100 phr of a terpolymer of Cto Cisoolefin derived units, p-alkylstyrene derived units and p-bromomehtylstyrene derived units; at least one filler such as carbon black, silica, precipitated silica, clay, or combinations thereof; and from 0. 1 to 3 phr of at least one thiourea. The composition can also include from 5 to 80 phr of at least one elastomer selected from natural rubbers, polyisoprene rubber, styrene butadiene rubber (SBR), polybutadiene rubber, isoprene butadiene rubber (IBR), styrene-isoprene-butadiene rubber (SIBR), butyl rubber, halogenated butyl rubber, butadiene-acrylonitrile-styrene rubber (SNBR), and mixtures thereof The composition can be cured by using one or a combination of curatives known in the rubber industry. For example, the composition may include from 0. 1 to 10 phr of at least one of a peroxide, sulfur, a metal oxide, or a combination thereof.

US Classification:

525/192000, 152/209100, 152/525000

Abstract:

The present invention is an elastomeric composition having a primary rubber component, a secondary rubber component, and an elastomeric component. More particularly, in one embodiment the elastomeric composition has from 50 to 95 phr natural rubber as the primary rubber component, from 5 to 40 phr of a copolymer of a Cto Cisoolefin and a para-alkylstyrene as the elastomeric component, and from 0 to 40 phr of polybutadiene as a secondary rubber component. In one embodiment, the copolymer includes a terpolymer of isobutylene, para-methylstyrene and para-bromomethylstyrene, wherein the para-bromomethylstyrene is present from 0.2 mol % to 3.0 mol %. Further, the composition desirably contains carbon black. The compositions are useful for tire treads and tire sidewalls having improved winter wear properties such as high DIN abrasion values and improved Tangent Delta values. The compositions are also useful in any application where high damping and high abrasion resistance is desirable, such as in hoses, belts, antivibrational mounts and shoe soles.
