Abstract
Official abstract text for this publication.
In one aspect, the present invention pertains to novel block materials comprising an aliphatic polycarbonate (APC) chain bound to a hydrocarbon. The invention also provides methods of making the block materials and using them as compatibilizers for polymer blends. In another aspect, the present invention encompasses methods of making blends of APCs with polyolefins. In certain embodiments, the methods comprise the step of blending one or more APCs with one or more polyolefins in the presence of a compatibilizer as described herein. In another aspect, the present invention encompasses novel blends of APCs with polyolefins. In certain embodiments, the blends comprise one or more APCs; at least one polyolefin and a compatibilizer as described herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of compatibilizing a blend of two or more polymers comprising the step of admixing with the polymers an effective amount of the block copolymer comprising the formula: where the moiety comprises an alternating copolymer of CO 2 and one or more epoxides; and the moiety consisting of a saturated or unsaturated hydrocarbon. 2. The method of claim 1 , wherein the blend of two or more polymers comprises at least one polyolefin and at least one aliphatic polycarbonate. 3. The method of claim 2 , wherein a polyolefin is selected from polyethylene and polypropylene. 4. The method of claim 2 , wherein the aliphatic polycarbonate is selected from poly(propylene carbonate); poly(ethylene carbonate); poly(cyclohexene carbonate); and blends or copolymers of two or more of the aliphatic polycarbonate.
