Title:
CURABLE COMPOSITION CONTAINING CYCLIC MULTIFUNCTIONAL MONOMER
Document Type and Number:
WIPO Patent Application WO/2022/163766
Kind Code:
A1
Abstract:
This curable composition contains (A) a side-chain-containing cyclic molecule that contains three or more side chains having a group that has an active hydrogen at the terminal, (B) a urethane prepolymer that has an iso(thio)cyanate on both terminals of the molecule, (C) a diol, and (D) an amino group-containing monomer. The present invention makes it possible to provide a curable composition that forms a cured body that has high abrasion resistance and that exhibits excellent mechanical properties, and in particular a curable composition that forms a cured body that can favorably be used in a polishing pad.
