Title:
LOW MOISTURE CONTENT POLYROTAXANE MONOMER AND CURABLE COMPOSITION COMPRISING SAID MONOMER
Document Type and Number:
WIPO Patent Application WO/2019/221249
Kind Code:
A1
Abstract:
The present invention is a polyrotaxane monomer (A) with a composite molecular structure comprising ring-shaped molecules and a shaft molecule that passes through the ring of the ring-shaped molecules and has bulky groups on both ends so that the rings do not detach, the polyrotaxane monomer being characterized in having a polymerizable functional group in the molecule and having a moisture content of 5000 ppm or less. With the present invention, it is possible to provide a polyrotaxane monomer with which a high productivity, high quality material can be produced in high yields while maintaining the superior mechanical characteristics of polyrotaxane monomers.
