Abstract:
A compatibilized blend comprising:A) a non-polar thermoplastic elastomer comprising a thermoplastic polyolefin homopolymer or copolymer and an olefin rubber which is fully crosslinked or partially crosslinked; and B) a polar thermoplastic polymer selected from the group consisting of thermoplastic polyurethane (TPU), chloro containing polymers, fluoro containing polymers, polyesters, acrylonitrile-butadiene-styrene copolymers, styrene-acrylonitrile copolymers, styrene-maleic anhydride copolymer, polyacetal, polycarbonate, and polyphenylene oxide; and C) a compatibilizer selected from the group consisting of a) a condensation copolymer of 10 to 90 weight % of a functionalized olefin polymer with 90 to 10 weight % of a polyamide, based on the total weight of functionalized polymer and polyamide, or b) a blend of a functionalized olefin polymer and a polyamide in the amounts defined under (a) or c) a mixture of (a) and (b), under the proviso that the functionalized polymer contains no less than 0.3 weight %, based on the total weight of the functionalized polymer, of at least one functional group-containing monomer.
