摘要:
A thermoplastic elastomer composition dynamically vulcanized to a gelation rate of 50 to 95% which is superior in heat resistance and durability while maintaining flexibility and superior in air permeation preventive property which can be efficiently used as, for example, a pneumatic tire as an air permeation preventive layer. In particular, a thermoplastic elastomer composition having a reduced particle size of the domain rubber is produced by a material having a high rubber ratio by mixing a composition (C) mixed under conditions of a ratio of melt viscosities of the rubber composition (A)/resin (B) of 0.8 to 1.2 and the formula (&phgr;A/&phgr;B)×(&eegr;B/&eegr;A)
摘要:
A thermoplastic resin elastomer/rubber laminate comprising a rubber layer containing 100 parts by weight of a rubber and 0.1-20 parts by weight of an antioxidant preblended thereto and a thermoplastic resin elastomer composition layer, obtained by laminating at least two layers of the rubber layer and the thermoplastic resin elastomer composition layer followed by heating and pressing, whereby the antioxidant migrates from the rubber layer to the thermoplastic resin elastomer composition layer to improve the weathering resistance as well as a pneumatic tire using the same as an inner liner.
