A pneumatic tire and an innerliner for use in a pneumatic tire are provided by the invention. The innerliner comprises a multilayer structure including a barrier layer and an adhesive layer. The barrier is a blend of high chlorine content chlorinated polyethylene elastomer and low chlorine-content chlorinated polyethylene elastomer. The adhesive can include a nitrile rubber composition or an ultra high molecular weight elastomer. The present invention more specifically discloses a pneumatic tire comprising a carcass and an innerliner, said innerliner comprising a multilayer structure including a barrier layer and an adhesive layer, the barrier layer comprising a blend of high chlorine content chlorinated polyethylene elastomer and low chlorine content chlorinated polyethylene elastomer, the high chlorine content chlorinated polyethylene elastomer having a chlorine content of between about 35 percent to about 45 percent and the low chlorine content chlorinated polyethylene polymer having a chlorine content of between about 25 percent to about 35 percent, wherein the high chlorine content polyethylene has a chlorine content which is at least 5 percentage points higher that the chlorine content of the low chlorine content polyethylene; the adhesive layer comprising a polymer composition for adhering the barrier layer to said rubber carcass; and wherein the innerliner provides an oxygen permeability of less than 250 cc-mil/100 in -atm-day at 65&deg; C. and good cold flexibility at &minus;40&deg; C.

Pneumatic tire and innerliner and method for manufacture

A polyester resin is disclosed containing graphite in sufficient quantities to reduce its infrared heat up time in the reheat-blow process. The amount of graphite added is from 0.1 to 15 ppm and the average particle size is from 0.1 to 20 microns. The polyester is useful to make bottle preforms for beverage containers. Methods of making the polyester resin are also disclosed using a masterbatch or liquid slurry addition technique.

Fast heatup polyesters using graphite as an additive

This invention is a composition, a kit to prepare the composition, cellular sheet made from the composition and thermoformed articles made from the sheet, in which the composition comprises polyethylene terephthalate, sufficient inert gas to give a sheet density of 0.4 to 1.25 gm/cc, a polytetrafluoroethylene nucleating agent and optionally a polyolefin additive and a heat stabilizer.

Cellularized polyesters

This invention is a composition and a kit to prepare the composition and articles made from the composition, which composition comprises polyethylene terephthalate, a nucleating agent having a defined Nucleation Index and optionally a polyolefin and a heat stabilizer. A particularly effective nucleating agent is polytetrafluoroethylene.

Nucleation of crystallization in polyesters

A deep stretch forming process for producing low distortion, biaxially oriented, heat set, hermetically sealable hollow containers of high molecular weight saturated linear polyesters comprised of deep stretching an injection molded heated contoured preform into a hollow die by means of a heated forming plunger, annealing or heat setting and then cooling the formed hollow container prior to said containers removal from said die.
