Patent number: 6066691Abstract: An anti-blocking agent comprising silicon dioxide or mixtures of silicon dioxide and zeolite is described, which is characterized in that it has a bimodal pore size distribution, the first maximum of the bimodal pore size distribution being in the pore size range <5 nm and the second maximum of the bimodal pore size distribution in the pore size range >6 nm. The anti-blocking agent is obtainable by micronizing a mixture comprising silicon dioxide of a certain pore size and silicon dioxide and/or zeolite having a different pore size. It can be produced together with lubricating agent as a combined anti-blocking and lubricating agent. Incorporation of the anti-blocking agent or of the combined anti-blocking agent and lubricating agent into a polymer in the form of a master batch is preferable.Type: GrantFiled: August 4, 1998Date of Patent: May 23, 2000Assignee: Grace GmbHInventors: Richard Sobottka, Georg Luers, Andreas Schmidt

Patent number: H1955Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Ziegler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50%, a Mw/Mn below 3, and a Mz/Mw below 2.Type: GrantFiled: July 31, 1996Date of Patent: April 3, 2001Assignee: Exxon Chemical Patents Inc.Inventors: Jeffrey Alan Middlesworth, Kevin Arthur Brady
