Patent number: 6288171Abstract: Random propylene thermoplastic copolymers can be used to increase the elongation to break and toughness of thermoplastic vulcanizates. Semi-crystalline polypropylene is a preferred thermoplastic phase. The rubber can be olefinic rubbers. Random thermoplastic polypropylene copolymers are different from conventional Ziegler-Natta propylene copolymers as the compositional heterogeneity of the copolymer is greater with Ziegler-Natta copolymers. This difference results in substantial differences in properties (elongation to break and toughness) between thermoplastic vulcanizates modified with random thermoplastic propylene copolymers and those modified with conventional Ziegler-Natta propylene copolymers. An increase in elongation to break results in greater extensibility in the articles made from a thermoplastic vulcanizate.Type: GrantFiled: July 1, 1998Date of Patent: September 11, 2001Assignees: Advanced Elastomer Systems, L.P., Exxon Chemical Patents, Inc.Inventors: Terry Finerman, Maria D.

Patent number: 6238789Abstract: A breathable, decorative wallcovering having a smooth, continuous, aesthetically appealing exposed surface which can be printed with a design or pattern having sharply defined edges, and having a relatively high moisture permeability, includes a porous polymeric ply fused to and supported by a nonwoven substrate ply which consists of an array of hydroentangled fibers. The porous polymeric ply is formed by thermally fusing a plastisol coating, which is applied to the nonwoven substrate ply, and which has a thickness sufficiently low to permit localized variations in fiber orientation and small variations in the thickness of the nonwoven substrate ply to cause the formation of a multiplicity of miniature discontinuities which are substantially invisible to the unaided eye and which are randomly distributed throughout the coating. The plastisol coating is, however, thick enough to allow the formation of a coating which upon thermal fusion provides a polymeric ply having a smooth continuous appearance.Type: GrantFiled: March 22, 1994Date of Patent: May 29, 2001Assignee: Omnova Solutions Inc.Inventor: Dan L. Jackson

-
Patent number: 6182728Abstract: A run flat tire has a plurality of reinforcing wedges located in the tire sidewall with the hardness of each wedge generally diminishing in the radially inward direction of the sidewall. Since the bead filler is harder than the radial innermost wedge, the hardness at generally the top of the bead filler increases in the radial inward direction. The reinforcing wedges partially overlap each other and can generally have any configuration. The changing of hardness of the radial wedges results in a wedge sequence and thus a more even strain distribution throughout the tire sidewall. This strain distribution extends the run flat life of the tire and also provides a good balance with other tire performance parameters.Type: GrantFiled: June 4, 1999Date of Patent: February 6, 2001Assignee: Hankook TireInventors: Thomas A. Williams, Jong Bok Park, Gary Day
