Abstract
Thermoplastic compositions are described comprising blends of styrene-acrylonitrile resin and nitrile rubber of high gel content.
Claims10
A thermoplastic composition comprising a blend of about 20 to about 65 parts by weight thermoplastic SAN resin comprising a polymer of styrene and acrylonitrile and about 75 to about 35 parts by weight nitrile rubber comprising a polymer of 1,3-butadiene or isoprene and vinyl nitrile monomer per 100 total parts by weight SAN resin and nitrile rubber in which the nitrile rubber is cured with rubber curative and has a gel content in toluene of at least 85%.
An elastoplastic composition comprising a blend of about 25 to about 40 parts by weight SAN resin comprising a polymer of styrene and acrylonitrile and about 75 to about 60 parts by weight rubber comprising a polymer of 1,3-butadiene or isoprene and vinyl nitrile monomer per 100 total parts by weight SAN resin and nitrile rubber in which the nitrile rubber is cured with rubber curative and has a gel content in toluene of at least 85% which composition is elastomeric and processable as a thermoplastic.
