    摘要： This invention is based upon the discovery that cyclized polyisoprene polymers can be incorporated into tire tread compounds to improve traction, treadwear, and resistance to tear. It is further based upon the discovery that cyclized polyisoprene polymers can be blended with halobutyl rubber and/or natural rubber and can be utilized in tire innerliner formulations. The present invention more specifically discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, at least one ply extending from bead to bead and sidwalls extending radially from and connecting said tread to said beads, wherein said tread is adapted to be ground-contacting, and wherein said tread is comprised of a sulfur cured rubber composition which is comprised of about 5 phr to about 50 phr of cyclized polyisoprene and about 50 phr to about 95 phr of at least one other rubbery polymer. The present invention further discloses a tire which is comprised of a generally toroidal-shaped carcass with an outer circumferential tread, two spaced beads, an innerliner, at least one ply extending from bead to bead and sidwalls extending radially from and connecting said tread to said beads, wherein said innerliner is comprised of a sulfur cured rubber composition which is comprised of about 5 phr to about 50 phr of cyclized polyisoprene and about 50 phr to about 95 phr of at least one other rubbery polymer selected from the group consisting of natural rubber and halobutyl rubber.

    摘要翻译： 本发明基于以下发现：环化聚异戊二烯聚合物可以并入轮胎胎面胶料中以改善牵引力，胎面磨损和耐撕裂性。 进一步基于以下发现：环化聚异戊二烯聚合物可与卤代丁基橡胶和/或天然橡胶共混，并可用于轮胎内衬配方中。 本发明更具体地公开了一种轮胎，其由具有外圆周胎面的大致环形胎体，两个间隔开的胎圈，从胎圈到胎圈延伸的至少一个帘布层和从所述胎面径向延伸并将所述胎面连接到所述胎圈的轮胎， 其中所述胎面适于与地面接触，并且其中所述胎面由硫磺固化的橡胶组合物组成，硫化橡胶组合物由约5phr至约50phr的环化聚异戊二烯和约50phr至约95phr的至少一种其它 橡胶状聚合物。 本发明还公开了一种轮胎，其包括通常为环形的胎体，其具有外周胎面，两个间隔开的胎圈，内衬层，至少一个从胎圈到胎圈延伸的帘布层和从所述胎面径向延伸并将所述胎面连接到所述胎面的侧壁 珠，其中所述内衬层由硫固化的橡胶组合物组成，其由约5phr至约50phr的环化聚异戊二烯和约50phr至约95phr的至少一种其它橡胶状聚合物组成，所述其它橡胶状聚合物选自天然橡胶 和卤代丁基橡胶。
