Abstract

Organosilicon compounds represented by the general formula: ##EQU1## and preparing process thereof were disclosed; where a lies in the range 1≦a≦3 and b lies in the range 0.001≦b ≦2,

R¹ are identical or dissimilar monovalent saturated or unsaturated hydrocarbons with 1-30 carbon atoms,

R² is a monovalent organic group represented by

CR.sup.3.sub.2 CR.sup.3 (H)CR.sup.3.sub.2 --R.sup.3,

R³ are hydrogen atoms or monovalent saturated hydrocarbon groups with 1-5 carbon atoms.

R⁴ are monovalent organic groups represented by the formula: ##STR1## R⁵ being identical to said R¹ or halogen atoms, alkoxy groups, carboxyl groups, hydroxyl groups or amino groups, d is an integer from 0 to 4 and c is an integer from 0 to 3.
