Patent ID: 6953541

Claim:
A method for preparing high scrap recycle content flexible polyolefin compositions comprising: creating a melt blend comprised of 15% to 50% by weight thermoplastic scrap material, up to 15% by weight poly(ethylene-co-vinyl acetate) and the remainder of the melt blend comprised of a blending composition; wherein the melt blend is formed by feeding said components to a melt compounding extruder operating at sufficient temperature, residence time and screw configuration to produce a homogenous melt blend; solidifying said melt blend; wherein the blending composition is comprised of from 40% to 60% by weight polypropylene, at least 40% by weight impact modifier and up to 15% by weight plasticizer; wherein the polypropylene is an impact polypropylene polymer with 5 to 7 percent by weight attached ethylene chains; wherein the impact modifier is an olefin copolymer of ethylene; wherein the plasticizer is selected from the group of compositions consisting of, tri-2-ethylhexyl trimellitate, butylbenzene sulfonamide, epoxidized soybean oil, octyl tallate, butyl tallate, octyl tallate and alkyl tallate; wherein the thermoplastic scrap material comprises granulated blends comprised of between 12 and 35% by weight polyamide; wherein the thermoplastic scrap material comprises up to 3% by weight polyester; wherein the thermoplastic scrap material comprises up to 5% by weight polypropylene; wherein the thermoplastic scrap material comprises up to 15% by weight poly(ethylene-co-vinyl acetate); and wherein the thermoplastic scrap material comprises up to 75% by weight poly(ethylene-co-vinyl acetate) filled with inorganic compositions wherein said inorganic compositions are further comprised of BaSO 4 and CaCO 3 and; wherein the flexible polyolefin composition so produced comprises at least 16 percent by weight of the polypropylene.
