Title:
CURABLE COMPOSITION CONTAINING IONIC-GROUP-CONTAINING ROTAXANE MONOMER, AND POLISHING PAD OBTAINED FROM SAID CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/096010
Kind Code:
A1
Abstract:
The present invention relates to a curable composition comprising: (A) a rotaxane monomer which has a composite molecular structure comprising cyclic molecules and an axial molecule extending through the rings of the cyclic molecules, the cyclic molecules each having both a polymerizable functional group and an ionic functional group; and (B) a polymerizable monomer having a polymerizable functional group capable of polymerizing with the polymerizable functional groups of the rotaxane monomer (A). The present invention can provide a curable composition that gives cured objects which have high wear resistance and have improved hydrophilicity while retaining the intact mechanical properties. In particular, it is possible to provide a curable composition capable of giving polyurethane resins (cured objects) suitable for use as polishing pads.
