Title:
COPOLYMER COMPOSITION, FOAM MOLDED BODY, CROSSLINKED MOLDED BODY, AND PRODUCTION METHODS OF THESE
Document Type and Number:
WIPO Patent Application WO/2023/136287
Kind Code:
A1
Abstract:
The present invention provides a copolymer composition which is characterized by containing: a copolymer (S) which comprises a constituent unit derived from ethylene (A), a constituent unit derived from an α-olefin (B) having 3 to 20 carbon atoms, and a constituent unit derived from a specific non-conjugated polyene (C), and satisfies the requirement (i) and the requirement (ii) shown below; a hydrosilyl group-containing compound (Y) which is an organohydrogen polysiloxane that has at least one silicon atom-bonded aralkyl group and at least two silicon atom-bonded hydrogen atoms in each molecule; and a platinum-based catalyst for hydrosilylation crosslinking. (i) (A)/(B) is 40/60 to 99.9/0.1. (ii) The mass percent concentration of the constituent unit derived from a non-conjugated polyene (C) is 0.07 to 10% by mass.
