COPOLYMER COMPOSITION, FOAM MOLDED BODY, CROSSLINKED MOLDED BODY, AND PRODUCTION METHODS OF THESE

Abstract: provided is a copolymer composition. the copolymer composition comprises a copolymer (s) which has a structural unit derived from an ethylene (a), a structural unit derived from an �-olefin (b) having 3 to 20 carbon atoms, and a structural unit derived from a specific non-conjugated polyene (c), and satisfies a requirement (i) and a requirement (ii), a hydrosilyl group-containing compound (y) which is an organohydrogenpolysiloxane having at least one silicon atom-bonded aralkyl group and at least two silicon atom-bonded hydrogen atoms in a molecule, and a platinum catalyst for hydrosilyl crosslinking. requirement (i) is where [a]/[b] is 40/60 to 99.9/0.1 requirement (ii) is where a mass percent concentration of the structural unit derived from the non-conjugated polyene (c) is 0.07% to 10% by mass.
