PLASTICIZED POLYOLEFIN COMPOSITIONS

摘要

A plasticized polyolefin composition comprising one or more polyolefins and one or more non-functionalized plasticizers where the non-functionalized plasticizer comprises C20 to C1500 paraffins having a Kinematic viscosity of 10 cSt or more at 100°C, a viscosity index of 120 or more and a specific gravity of from 0.700 to 0.860, and where the polyolefin has a crystallinity of 5 to 80 %, and wherein elastomers are substantially absent from the composition, and ethylene homopolymers and copolymers having an Mw of from 500 to 10,000 are present at less than 0.5 wt% (based upon the weight of the polyolefin, ethylene polymer and non-functionalized plasticizer) and wherein the polyolefin is polypropylene having an Mw of 50,000 to 2,000,000 g/mol.
