Abstract

The invention provides organosilicon compounds of the formula: ##STR1## in which: n is 1, 2 or 3; PA1 each R, which may be identical or different, is a monovalent organic group which contains a carbon-carbon double bond and from 2 to 10 carbon atoms; PA1 each R.sub.1, which may be identical or different, is a straight or branched alkyl radical optionally substituted by one or more halogen atoms or cyano groups; an aryl radical or an alkylaryl radical optionally substituted by one or more halogen atoms; PA1 R.sub.2 is a straight or branched divalent alkylene or alkylidene radical possessing up to 4 carbon atoms; PA1 X is a divalent radical consisting of, or containing, at least one hetero-atom selected from oxygen, sulphur and nitrogen atoms, the radical being attached to the radical R.sub.2 via a said hetero-atom; PA1 G is an organic radical of valency (m+1) possessing from 1 to 30 carbon atoms; PA1 m is 1, 2 or 3; PA1 and each Y, which may be identical or different, is a functional group selected from ##STR2## wherein R.sub.3 represents a hydrogen atom or a straight or branched alkyl radical possessing up to 6 carbon atoms and R.sub.4 represents an alkyl radical possessing up to 4…
