RADICALLY POLYMERIZABLE POLYETHER, METHOD FOR PRODUCING SAID RADICALLY POLYMERIZABLE POLYETHER, POLYMERIZABLE COMPOSITION COMPRISING SAID RADICALLY POLYMERIZABLE POLYETHER AND RADICALLY POLYMERIZABLE VINYL MONOMER, AND COPOLYMER, MOLDED ARTICLE AND FILM EACH FORMED BY RADICAL POLYMERIZATION OF SAID POLYMERIZABLE COMPOSITION

摘要

Provided is (1) a radically polymerizable polyether which imparts excellent mechanical properties including excellent transparency, a high degree of elongation at break and high bending strength to a copolymer produced by the radical polymerization of a radically polymerizable monomer, and a method for producing the radically polymerizable polyether; (2) a polymerizable composition comprising the radically polymerizable polyether and a radically polymerizable vinyl monomer, which enables the formation of a copolymer having excellent mechanical properties; and (3) a copolymer, a molded article and a film, each of which comprises the copolymer.
