Polysiloxane-containing rubber composition

A pneumatic tire having a non-black rubber composition provided at the at least one portion thereof, at least a portion of said non-black rubber composition comprising 100 part by weight of at least one synthetic rubber and 5 to 100 parts by weight of strontium aluminate or calcium aluminate a long afterglow phosphorescent substance having an average particle size of 1 to 100 Am and having no substantial amounts of carbon black and staining antioxidant, and crosslinked with a crosslinking agent other than sulfur or a pneumatic tire having two or more layer structure of a surface layer of the above phosphorescent rubber composition layer and a lower layer of a blight-colored reflecting layer or the transparent or translucent cover layer and the under phosphorescent rubber composition layer.

Pneumatic tire using long afterglow phosphorescent rubber composition

Process of production of pneumatic tire

A polysiloxane composition comprising (i) an alkoxysilyl group-containing polysiloxane containing at least six siloxane structures having the following formula (I) in a molecule

Polysiloxane composition and rubber composition and resin composition

Rubber compositions for footwear, conveyor belt covers, rolls, hoses, cables, rubberized fabrics, and grips containing (A) an elastomer, (B) 5 to 150 parts by weight of a filler, and (C) a polysiloxane represented by the formula (I):

Rubber composition

A rubber composition having improved properties containing a starting rubber (e.g., diene rubber) and a compounding agent consisting of a silane coupling agent and a carbon black, calcium carbonate or stearic acid powder impregnated with a polysiloxane having the following alkoxysilyl group (I) and/or acyloxysilyl group (II) and having an average degree of polymerization of 3 to 10,000:

Process for production of rubber composition

A rubber composition containing a diene rubber and a modified polyisobutylene rubber having a functional group capable of reacting with a silanol group present on a surface of silica, together with a precipitated silica or a silica-adhered carbon black, having a tan .delta. at 60.degree. C. of 0.2 or more.

Rubber composition containing modified polyisobutylene rubber

A rubber composition having improved properties containing a starting rubber (e.g., diene rubber) and a compounding agent comprising a mixture of a polysiloxane having the following alkoxysilyl group (I) and having an average degree of polymerization of 3 to 10,000:

The invention provides a laminate suitable for use with a pneumatic tire having an inner liner or like air-impermeable layer capable of, for example, maintaining a requisite air pressure. The laminate I of the invention includes laminated films and a rubber layer (R), the laminated films being made of a gas barrier layer (A) and an adhesive layer (B), the layer (B) being provided on at least one side of the layer (A), the layer (A) being formed of at least one member selected from polyamide resins, polyester resins, polyarylate resins, polyamide-based alloys and polyester-based alloys, the laminated films being irradiated in at least one periphery with an electron beam, and the adhesive layer (B) being heat-bonded to the rubber layer (R). The laminate II of the invention includes laminated films and a rubber layer (R), the laminated films being made of a rubber-adhering layer (D), an adhesive layer (B) and a gas barrier layer (A), the layers (D), (B) and (A) being laminated in this order with a structure of at least three layers, the rubber-adhering layer (D) being formed of at least one polyolefin resin, the gas barrier layer (A) being formed of at least one member selected from polyamide resins, polyester resins, polyarylate resins, polyamide-based alloys and polyester-based alloys, the laminated films being irradiated in at least one periphery with an electron beam, and the rubber-adhering layer (D) being heat-bonded to the rubber layer (R).
