Abstract
Moisture-curable resin compositions comprising (a) a moisture-curable polymer having at least one hydrolysable silyl group; (b) a reactive modifier; (c) a catalyst for catalyzing the reaction between the moisture-curable polymer (a) and reactive modifier (b) under curing conditions; and cured compositions produced by contacting such resin compositions with water are disclosed. The moisture-curable resin composition is useful in the production of adhesives, including hot melt adhesives, primers, sealants, and coatings.
