Title:
METHOD FOR PRODUCING OPTICAL STABILIZER COMPOSITION, AND METHOD FOR PRODUCING CURING COMPOSITION
Document Type and Number:
Japanese Patent JP2013006887
Kind Code:
A
Abstract:

To enable a high-molecular weight hindered amine-based optical stabilizer to be well dissolved in a curing composition containing a modified silicone polymer.

A mixture containing a polyoxyalkylene (mono)polyol (X) and a hindered amine-based optical stabilizer having a molecular weight of 1,000 to 5,000 is heated at a temperature of the melting point or higher of the hindered amine-based optical stabilizer in the mixture to dissolve the hindered amine-based optical stabilizer to thereby obtain an optical stabilizer composition, which is mixed with a polymer-containing liquid containing a polyoxyalkylene polymer (P) having a hydrolyzable silicon group.
