ABSTRACT:
A curable vinyl polymer having at least one silyl group of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each a hydrogen or a monovalent hydrocarbon radical having 1 to 10 carbon atoms, X is a group selected from halogen, alkoxy, acryloxy, aminoxy, phenoxy, thioalkoxy and amino groups; and "a" is a whole number equal to 0, 1 or 2, and having molecular weight of between 200 and 30,000, preferably between 1,500 and 25,000; and method for producing same, and products comprised of same; and wherein said method comprises reacting hydrosilane represented by the formula: ##STR2## wherein the same designations as above apply, with a polymer having carbon-carbon double bonds in the terminal or side chains of the polymer in which the main chain is a vinyl polymer having a molecular weight of between 200 and 30,000, and at a temperature of between 50.degree. and 150.degree. C.
