Abstract
Flexible blend compositions are provided having a Shore A hardness of less than or equal to about 90. The compositions are blends of an overpolymer and/or graft polymer with a plasticizer or blending agent. The overpolymer has an ethylene copolymer substrate overpolymerized with a vinyl chloride type monomer or comonomer and optionally including an acrylate comonomer. The compositions are distinguished by an absence of shrinkage in hot oil. The compositions generally tend to swell in hot oil.
