<p>PROBLEM TO BE SOLVED: To obtain a resin composition which can rapidly cure at ordinary temperature and has a long pot life by incorporating a block copolymer containing a polymer part having epoxy, hydroxyl, or hydrolyzable silyl groups and a polyorganosiloxane part. SOLUTION: This composition contains a block copolymer having a polymer part having epoxy, hydroxyl, or hydrolyzable silyl groups and a polyorganosiloxane part in the molecular chain and a polyfunctional amine compound. The block copolymer is obtained by polymerizing 10-50 wt.% epoxy- containingα,β-ethylenically unsaturated monomer, 1-20 wt.% hydroxyl-containingα,β-ethylenically unsaturated monomer, 1-10 wt.% hydrolyzable-silyl-containingα,β-ethylenically unsaturated monomer 0.05-20 wt.% polyorganosiloxane, and 0-87.95 wt.% otherα,β-ethylenically unsaturated monomers in the presence of a combination of a polymeric azo initiator represented by the formula (wherein x=10-300; and n=1-20) with a radical initiator.</p> |
