Abstract
Official abstract text for this publication.
A new additive for plastics (for example, polyethylene) is prepared by reacting a fatty acid ester of glycerol (such as glycerol monostearate) with a source of a reactive divalent metal selected from zinc, calcium, and magnesium. In an embodiment, Zinc oxide is the reactive divalent metal and the reaction is conducted in the presence of an acid such as zinc acetate. In one embodiment, a molar excess of zinc oxide (compared to the fatty acid ester) is used. The additive is suitable for use in the preparation of injection molded parts, rotomolded parts, and films.
First claim
Opening claim text (preview).
What is claimed is: 1. A polyethylene composition comprising a polyethylene polymer or copolymer and an additive prepared by the reaction of a) a fatty acid ester of glycerol; with b) a divalent metal selected from zinc, calcium, and magnesium. 2. The polyethylene composition of claim 1 wherein the molar ratio of said fatty acid ester of glycerol to said divalent metal is from about 1/3 to about 3/1. 3. The polyethylene composition of…
