<p>Compositions comprising blends of about 5-75 parts by weight of thermoplastic crystalline polyester and about 95-25 parts by weight of cured epichlorohydrin rubber per 100 total parts by weight polyester and cured rubber exhibit a valuable combination of properties. Compositions comprising 60 or more parts by weight of polyester are thermoplastic compositions exhibiting improved impact resistance. Compositions comprising 40 or more parts by weight of cured epichlorohydrin rubber are elastomeric. When compositions containing high proportions of rubber are statically cured, for example in molds, thermoset compositions are obtained; if such compositions are dynamically cured, i.e., if the blend is masticated while the rubber is cured, elastoplastic compositions, which exhibit elastomeric properties and yet are processable as thermoplastics, are obtained.</p> |
