Title:
硬化性組成物及び透明耐熱材料の製造方法
Document Type and Number:
Japanese Patent JP6378667
Kind Code:
B2
Abstract:
The present invention provides a curable composition, which contains a crosslinking aid (B) containing three or more allyl groups in the molecule in an amount of 1 to 50 parts by mass, polyfunctional (meth)acrylic compound (C) in an amount of 5 to 50 parts by mass, and photopolymerization initiator (D1) and/or thermal polymerization initiator (D2) in an amount of 0.1 to 10 parts by mass, respectively, as a polymerization initiator (D) to 100 parts by mass of allyl group-terminated allyl ester oligomer (A);
wherein the crosslinking aid (B) containing allyl group is a compound containing three or more allyl groups in a molecule;
wherein the content of impurities derived from the crosslinking aid (B) in the curable composition is less than 0.1 mass%;
wherein the content of the (meth)acrylic compound containing a hydroxyl group in a molecule (C1) in the curable composition is 0.5 to 30 mass%. By polymerizing and curing the curable composition of the present invention, it is possible to obtain a film or sheet material having a transparency required for optical applications, high surface hardness, excellent heat resistance and low linear expansion coefficient.
