Patent ID: 8653189

Claim:
An oil-extended polymer blend composition comprising: a. as elastomeric linear styrene-butadiene-styrene triblock copolymer, the triblock copolymer having a styrene content within a range of from 15 percent by weight to 23 percent by weight, based upon block copolymer weight, and a molecular weight within a range of from 90,000 to 130,000; b. a thermoplastic polymer selected from a group consisting of polystyrene homopolymer, an ethylene-based polymer consisting of high-pressure low density polyethylene, high density polyethylene, linear low density polyethylene, ultra-low density polyethylene, ethylene/alpha-olefin copolymers wherein the alpha-olefin contains from three to twenty carbon atoms and ethylene/alpha-olefin interpolymers, a propylene-based polymer including homopolymer polypropylene, propylene/alpha-olefin copolymers wherein the alpha-olefin contains two (2) or from four (4) to eight (8) carbon atoms, and ethylene/vinyl acetate copolymers that have an ethylene content within a range of from 70 percent by weight to 93 percent by weight, based upon ethylene/vinyl acetate copolymer weight; and c. an extender oil, the extender oil being present in an amount within a range of from 4 percent by weight to 20 percent by weight, based upon total composition weight, wherein the styrene-butadiene-styrene triblock copolymer is present in an amount within a range of from 60 percent by weight to 85 percent by weight, based upon total composition weight.
