Abstract
Organic silicon compounds which are expressed by the general chemical formulae (I) or (II): ##STR1## wherein R.sup.1 is a monovalent organic group with 1 to 8 carbon atoms; R.sup.2, R.sup.3 and R.sup.4 in each equation are independent and either a monovalent organic group with 1 to 8 carbon atoms or a siloxyl group expressed by ##STR2## wherein R.sup.5, R.sup.6 and R.sup.7 are independent in each equation and they are a monovalent organic group with 1 to 8 carbon atoms; and a is either 0, 1 or 2. The novel organic silicon compounds possess both a polymerizable double bond and organopolysiloxane within the same molecule. These compounds are superior in their polymerizability and copolymerizability and are useful as polymer reforming agents.
