Abstract
A composition comprising discrete particles of elastomeric triblock copolymer, the particles having a Shore A hardness of less than 30 suspended in a continuous phase matrix of noncellular elastomeric polyurethane polymer, in which the triblock copolymer has the configuration A-X-A in which block A is polystyrene and block X is a polymer of butadiene, isoprene or copolymer of ethylene and butylene; the final composition having a Shore A hardness of less than 20.

A composition comprising discrete particles of elastomeric triblock copolymer, the particles having a Shore A hardness of less than 30 suspended in a continuous phase matrix of noncellular elastomeric polyurethane polymer, in which the triblock copolymer has the configuration A-X-A in which block A is polystyrene and block X is a polymer of butadiene, isoprene or copolymer of ethylene and butylene;
- the final composition having a Shore A hardness of less than 20.
A kit comprising components 1) and 2) wherein component 1) is a triblock copolymer particles wherein the copolymer has the configuration A-X-A in which block A is polystyrene and block X is a polymer of butadiene, isoprene or copolymer of ethylene and butylene, and which said triblock copolymer has a Shore A hardness of less than about 30 and component 2) is a polyurethane which has a Shore A hardness of less than about 20;
- each component 1) and 2) being present in an amount sufficient to form a molded composition having discrete particles of component 1) in a noncellular continuous phase matrix of component 2) wherein said molded composition has a Shore A hardness of less than 20 and wherein the said composition is sufficient for a single use in a mold.
