Abstract
Improved thermoplastic compositions comprising blends of neutralized acrylic copolymer rubber and polyvinylchloride are described.
Claims13
A thermoplastic composition comprising a blend of about 20 to 98 parts by weight of at least 10% partially neutralized acid containing acrylic-olefin copolymer rubber, and about 80 to 2 parts by weight of polyvinylchloride (PVC) per 100 parts by weight of said rubber and PVC combined.
An elastoplastic composition comprising a blend of neutralized acid containing acrylic-olefin copolymer rubber, in an amount sufficient to impart rubberlike elasticity up to 98 weight percent of the composition,, and PVC, in an amount up to 50 weight percent of the composition, with the proviso that when the amount of PVC exceeds the amount of rubber, sufficient plasticizer is present to impart rubberlike elasticity to the composition.
