Abstract: The present invention relates to a tire with a colored sidewall joined with a plurality of colored grooves in its tread. In particular, the present invention relates to a tire of a black-colored rubber composition having a non-black colored sidewall portion which is integral with a plurality of non-black colored grooves of a tread of lug and groove configuration. For said tread, at least a portion of the visible surface of a plurality of tread grooves, exclusive of the outer surface portion of said carbon black reinforced rubber lugs intended to be ground-contacting, is of a non-black colored, synthetic amorphous silica reinforced rubber composition exclusive of carbon black. For said colored sidewall and plurality of connecting tread groove combination, said tread groove and sidewall may be of the same or different non-black color(s). In one aspect, said non-black visible surface of said tread grooves and connecting sidewall contains an elastomeric brominated copolymer of isobutylene and p-methyl styrene in combination with an organo phosphite compound.

Abstract: This invention relates to a pneumatic tire having a built-in sealant layer and its preparation. The sealant layer precursor is a layer of a butyl rubber based composition which contains an organoperoxide. The butyl rubber of said precursor is a copolymer of isobutylene and isoprene containing from about 0.5 to about 5, alternately less than 1, mole percent isoprene. The precursor composition contains carbon black and/or coal dust and may contain a dispersion of liquid conjugated diene polymer (e.g. liquid cis 1,4-polyisoprene polymer), short fibers and/or hollow glass microspheres. A layer of the sealant precursor is built into the tire between a sulfur vulcanized halobutyl rubber innerliner and conjugated diene-based rubber of the tire carcass. The butyl rubber of the sealant precursor is partially depolymerized by the organoperoxide during the elevated temperature vulcanization of the tire to form the built-in sealant layer. In one aspect of the invention, said uncured butyl rubber sealant precursor layer composition has a storage modulus G′ (80° C.) in a range of about 100 to about 400 kPa and said partially depolymerized butyl rubber sealant layer composition has a storage modulus G′ (80° C.) in range of about 5 to about 50 kPa.

Abstract translation: 本发明涉及具有内置密封剂层的充气轮胎及其制备方法。 密封层前体是含有有机过氧化物的基于丁基橡胶的组合物层。 所述前体的丁基橡胶是异丁烯和异戊二烯的共聚物，其含有约0.5至约5，交替少于1摩尔％的异戊二烯。 前体组合物含有炭黑和/或煤粉，并且可以含有液体共轭二烯聚合物（例如液体顺式1,4-聚异戊二烯聚合物），短纤维和/或中空玻璃微球体的分散体。 在硫化硫化的卤化丁基橡胶内衬和轮胎胎体的共轭二烯系橡胶之间的轮胎中内置有密封剂前体层。 在轮胎的高温硫化期间，密封剂前体的丁基橡胶被有机过氧化物部分地解聚以形成内置的密封剂层。 在本发明的一个方面，所述未固化的丁基橡胶密封剂前体层组合物的储能模量G'（80℃）在约100至约400kPa的范围内，所述部分解聚的丁基橡胶密封剂层组合物具有储能模量 G'（80℃）范围为约5至约50kPa。
