## CPC

- C07F 7/1804: {Compounds having Si-O-C linkages (Si-O-acyl linkages C07F7/1896)}
- C07F: ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM OR TELLURIUM (metal-containing porphyrins C07D487/22)

## Abstract

Disclosed is an organosilicon compound represented by the general formula ##STR1## wherein m and n are each an integer of 1 to 5, R.sup.1 and R.sup.2 are each independently an alkyl group having 1 to 3 carbon atoms or allyl, and a is an integer of 0 to 2. This organosilicon compound is a novel compound capable of affording a photopolymerizable organopolysiloxane of high quality.

## Claims

### Claim 1

An organosilicon compound represented by the following general formula: ##STR7## wherein m and n are each an integer of 1 to 5, R.sup.1 and R.sup.2 are each independently an alkyl group having 1 to 3 carbon atoms or allyl, and a is an integer of 0 to 2.

### Claim 2 (depends on 1)

A process for preparing an organosilicon compound represented by the general formula described in claim 1, which process is characterized by a condensation reaction of a vinyl ether containing an end hydroxyl group and represented by the general formula
CH.sub.2 =CH--O--(CH.sub.2).sub.m --OH
with a silane compound containing an end isocyanate group and represented by the general formula ##STR8## in which formulae R.sup.1, R.sup.2 a, m and n are as defined in claim 1.
