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

The present invention provides: (1) a radically polymerizable polyether which can impart 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 including excellent transparency, a high degree of elongation at break and high bending strength; and (3) a copolymer, a molded article and a film, each of which comprises the copolymer.The number average molecular weight of the radically polymerizable polyether is adjusted to a value falling within a specified range, and the amount of a (meth)acryloyl group to be introduced is adjusted to a value falling within a specified range. A polymer, a molded article and a film each having excellent mechanical properties including excellent transparency, a high degree of elongation at break and high bending strength can be produced using the radically polymerizable polyether.
