    Abstract: Pneumatic rubber tire with a tread composed of a rubber blend of a base of at least two synthetic elastomers composed of (i) specialized isoprene/butadiene copolymer elastomer having a low Tg in a range of about -70.degree. to about -100.degree. C. and (ii) a diene based elastomer having a Tg in a range of about -5.degree. to about -30.degree. C. together with a minor amount of natural cis 1,4-polyisoprene rubber. Selection of the base of the said two synthetic elastomers having spaced apart, or spatially defined, Tg's of at least 40.degree. C. is an important feature of the tread rubber blend. Representative examples of contemplated elastomers with Tg's in a range of about -5.degree. to about -30.degree. C. are 3,4-polyisoprene elastomer, styrene/isoprene copolymer elastomer and high vinyl polybutadiene elastomers.In one aspect, the tread rubber blend is reinforced with reinforcing filler composed of carbon black or a combination of carbon black and silica accompanied by a coupling agent.

    Abstract: It is often desirable to utilize accelerators in the sulfur vulcanization of unsaturated rubbers. In many cases a primary accelerator is used in combination with another accelerator, called a secondary accelerator or activator, which further increases the rate of vulcanization. It has been determined that compounds having the structural formula:NH.sub.2 --A--NH--(CH.sub.2).sub.x NH].sub.n A--NH.sub.2wherein x is 2 or 3, wherein n is an integer from 1 to 100, and wherein A represents an alkylene group containing from 1 to 20 carbons atoms, act as secondary accelerators in the vulcanization of unsaturated rubbers. For example, it has been determined that 4,7-diaza-decane-1,10-diamine is a particularly desirable secondary accelerator.

    Abstract: There is disclosed the use of esters especially methyl esters of rosin acids as total or partial replacements for oil in rubber formulations. Vulcanizate properties, low temperature performance, and processibility are comparable when using either the rosin ester or an aromatic oil, however, the rosin ester extended rubber demonstrates improved abrasion resistance and flex resistance.
