Publication number: 20080064796Abstract: Polymer materials that have been previously melt formed and cooled, can be reused in subsequent melt processes without undue degradation in one or more aesthetic or functional properties. The addition of phosphorous facilitates the reuse of the previously melt formed and cooled mixture of polymer material, e.g., commingled post consumer regrind and/or commingled plant scrap regrind. The processed mixture can then be reused in a significantly higher amount (than is possible without the phosphorous material) in a subsequently melt formed article without producing an undesirable amount of, for example yellowing, haze and/or reduction in melt viscosity. The reprocessed material may further provide increased layer compatibility in a subsequently formed multilayer article.Type: ApplicationFiled: September 11, 2006Publication date: March 13, 2008Applicant: Graham Packaging Company, LPInventors: Philip D.

Patent number: 6103798Abstract: Thermoplastic compositions are provided containing a saturated hydrocarbon amine oxide and stabilizer compositions are provided containing a saturated hydrocarbon amine oxide and a second stabilizer. The thermoplastic compositions exhibit good melt flow rate stability during processing and are useful for making molded and extruded articles. The stabilizer compositions are useful for addition to thermoplastics for the stabilization thereof. A method is also provided for stabilizing thermoplastic compositions and involves admixing a hydrocarbon amine oxide with a thermoplastic resin. The saturated hydrocarbon amine oxides are preferably trialkyl amine oxides. The thermoplastic resin is preferably a polyolefin resin.Type: GrantFiled: May 26, 1998Date of Patent: August 15, 2000Assignee: General Electric CompanyInventors: Vaikunth S. Prabhu, Roger W. Avakian
