CURABLE COMPOSITION, AND CURED PRODUCT THEREOF

摘要

The present invention provides a curable composition containing oxyalkylene-based polymer (A) having more than one reactive silicon group represented by the formula (1): —SiR1aX3-a on average in one molecule, (meth)acrylate-based polymer (B) having a reactive silicon group represented by the formula (2): —SiX3 and a reactive silicon group equivalent of not less than 0.30 mmol/g, and high-molecular weight plasticizer (C) having 0-1 reactive silicon group on average in one molecule (the groups in the formulas (1) and (2) are as defined in the DESCRIPTION).

主权项

1. A curable composition comprising:
oxyalkylene-based polymer (A) having more than one reactive silicon group on average in one molecule, wherein the group is a dimethoxymethylsilyl group, (meth)acrylate-based polymer (B) having a reactive silicon group represented by formula (2):
—SiX3  (2) wherein each X is independently a hydroxy group or a hydrolyzable group, wherein a reactive silicon group equivalent is not less than 0.30 mmol/g, and high-molecular weight plasticizer (C1) having more than 0 and not more than one reactive silicon group on average in one molecule, wherein the group is a dimethoxymethylsilyl group.
