ABSTRACT:
Polyorganosiloxane polymers which include at least one group of the formula: ##STR1## where R.sup.1 is an organo group; R.sup.2 is alkylene or alkenylene; G is a n+1 valent hydrocarbon, oxyhydrocarbon or poly(oxyhydrocarbon) radical in which some or all of the hydrogen atoms may optionally be substituted by halogen atoms; R.sup.3 is H or an organic functional group, particularly polymerizable groups, polymerization accelerating groups or polymerization initiating groups; n is an integer of 2 or more provided that when n is 2 and one of R.sup.3 is H, the other R.sup.3 group is also H; and a is 0, 1 or 2.
Additional polyorganosiloxane polymers include at least one group of the formula: ##STR2## where R.sup.4 R.sup.5 are H or a mono valent hydrocarbon group.
