    Abstract: The subject invention discloses the use of syndiotactic-1,2-polybutadiene in the supporting carcass and/or innerliner of a tire. The incorporation of syndiotactic-1,2-polybutadiene into rubber compositions which are utilized in the supporting carcass or innerliner of tires greatly improves the green strength of those compositions. The incorporation of syndiotactic-1,2-polybutadiene into halogenated butyl rubbers which are utilized as innerliner compositions also greatly improves the scorch safety of such compositions. The subject invention more specifically discloses a pneumatic rubber tire which comprises a circumferential rubber tread, a supporting carcass therefor, two spaced beads, two rubber sidewalls connecting said beads and an innerliner; wherein said supporting carcass is comprised of from 1 to 25 phr of syndiotactic-1,2-polybutadiene having a melting point which is within the range of 120.degree. C. to 190.degree. C. and at least one rubber selected from the group consisting of polyisoprene, styrene-butadiene rubber, and polybutadiene rubber.

    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.
