Patent number: 6235822Abstract: Gaskets comprising either at least one homogeneously branched ethylene polymer or at least one elastic substantially linear ethylene polymer, at least one ethylene/carboxylic acid interpolymer; and at least one slip agent are disclosed. These gaskets may also contain enhanced polyethylenes produced by the direct polymerization of various combinations of novel elastic substantially linear olefin polymers in multiple reactors using either single or multiple catalysts. These gaskets may also be comprised of at least one ethylene polymer and at least one ionomer. The above mentioned gaskets may also contain slip agents and/or foaming agents. The gaskets are particularly useful for sealing food and liquid containers and do not contribute to taste and/or odor of the packaged product, which is especially useful in food-stuff applications.Type: GrantFiled: July 26, 1999Date of Patent: May 22, 2001Assignee: The Dow Chemical CompanyInventors: Alan R. Whetten, Ronald P. Markovich, Steve M. Hoenig, Edward E. Greene

Patent number: 5935505Abstract: Modified polymer compositions having good flowabilty, impact performance and modulus made from at least one polyolefin (e.g., high density polyethylene or polypropylene) blended with minor amounts of either at least one homogeneous linear ethylene/C.sub.5 -C.sub.20 .alpha.-olefin or at least one substantially linear ethylene/C.sub.3 -C.sub.20 .alpha.-olefin polymer are disclosed. The compositions are suitable for thermoformed or molded thinwall applications such as drinking cups, lids, and food containers where the flow length to wall thickness ratios are greater than about 180:1. A process of making thin wall articles is also disclosed.Type: GrantFiled: November 26, 1997Date of Patent: August 10, 1999Assignee: The Dow Chemical CompanyInventors: Alan R. Whetten, Stephanie C. Cirihal, Stephen M. Hoenig, Ronald P. Markovich
