Polymer alloy, crosslinked articles, and fuel hoses

摘要

A polymer alloy formed by containing 40 to 90 wt % of a nitrile group-containing copolymer rubber (A) and 10 to 60 wt % of an acrylic resin (B); wherein said acrylic resin (B) contains at least 50 wt % of (meth)acrylic ester monomer unit and 1 to 27 wt % of alpha,beta-ethylenically unsaturated nitrile monomer unit is provided, by which a polymer alloy having excellent balance of resistance to cold, ozone, gasoline penetration and fuel oil and suitable as a material for fuel hoses can be provided.
