The method includes: reacting a poly(alkyl vinylether-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(alkyl vinylether-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(alkyl vinylether-co-maleimide) polymer product with an extender oil sufficient to form the gel. The present invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.Type: GrantFiled: November 17, 1998Date of Patent: February 20, 2001Assignee: Bridgestone CorporationInventors: Xiaorong Wang, Victor J. Foltz, Terrence E. Hogan

Patent number: 6191218Abstract: The invention is directed towards a method for improving hot tack in blown polyethylene films. Accordingly, a nucleating agent and polyethylene are combined to form a melt from which the film is blown. The method comprises forming a melt of polyethylene and a nucleating agent selected from the group consisting of dibenzylidene sorbitol, paramethyldibenzylidene sorbitol, dimethyldibenzylidene sorbitol, ethylene copolymers containing grafted maleic anhydride, ethylene copolymers containing grafted acrylic acid, and mixtures thereof. Polyethylene films having increased hot tack can be blown therefrom.Type: GrantFiled: July 14, 1998Date of Patent: February 20, 2001Assignee: Exxon Research and Engineering CompanyInventor: Arnold Lustiger

Patent number: 6191224Abstract: Novel polymer compositions for controlling or correcting dispersion mismatch between the composition and a side-fiber polished optical fiber are disclosed. The polymer compositions contain an infrared absorbing dye having an absorption maximum from about 900 to about 1200 nm and and a polar olefin copolymer containing monomers which are formed from polar olefins having an ester, benzene, or halogen substitutent attached. A method for controlling the dispersion exhibited by the novel polymer compositions is also disclosed. The method includes forming the polymer composition over an exposed surface of an optical fiber. Dispersion is controlled by controlling the amount of dye present in the polymer composition. Also disclosed is an optical device from which improvements in the uniformity of spectral response and performance are observed across a wavelength band. The optical device includes the polymer composition formed over an optical fiber.Type: GrantFiled: August 25, 1998Date of Patent: February 20, 2001Assignee: Molecular OptoElectronics CorporationInventors: Kwok Pong Chan, David G.
