ABSTRACT:
There is disclosed a method for the preparation of an organosilicon polymer having the structure ##STR1## wherein each R.sup.1 is a monovalent hydrocarbon group, R.sup.2 is an alkylene group, R.sup.3 is selected from hydrogen, an alkenyl group or a hydroxyl group, m is zero or greater and n is 1 or more, said method comprising:
reacting
(A) diorganosiloxane having the general formula ##STR2## (B) an unsaturated aliphatic hydrocarbon having 3 to 10 carbon atoms that contains 2 carbon-carbon double bonds and an unsaturated aliphatic hydrocarbon having 2 to 10 carbon atoms that contains 1 carbon-carbon triple bond, said reaction taking place in the presence of
(C) a hydrosilylation-reaction catalyst.
