Publication number: 20030087976Abstract: New cross-linked polymeric foam compositions, and methods for making the same, are provided. The new compositions utilize novel cross-linked polyolefin copolymers and show improvements in strength, toughness, flexibility, heat resistance and heat-sealing temperature ranges as compared to conventional low density polyethylene compositions. The new compositions also show processing improvements over linear low density polyethylene. The novel polyolefins, which are essentially linear, comprise ethylene polymerized with at least one alpha-unsaturated C3 to C20 olefinic comonomer, and optionally at least one C3 to C20 polyene, and exhibit, in an uncross-linked sense, a resin density in the range of about 0.86 g/cm3 to about 0.96 g/cm3, a melt index in the range of about 0.5 dg/min to about 100 dg/min, a molecular weight distribution in the range of from about 1.5 to about 3.5, and a composition distribution breadth index greater than about 45 percent.Type: ApplicationFiled: November 9, 2001Publication date: May 8, 2003Applicant: Sentinel Products Corp., a New York corporationInventors: John D.

Patent number: 6531520Abstract: The invention relates to polymer blends which can be used both in foamed and unfoamed states as a replacement for conventional EPDM and other elastomers. The composition of the blend includes a single-site catalyzed polyolefin resin having a density of below 0.878 g cm−3 and up to 40 weight percent a polyolefin including ethylene and propylene. The polymer blend is cross-linked. The polymer blends are formable-and foamable. The use of sulfur to vulcanize the polymer blend is not necessary. The polymer blends can be used to make foam for floatation or for making gaskets.Type: GrantFiled: January 25, 2002Date of Patent: March 11, 2003Assignee: Sentinel Products CorporationInventors: John D.
