Abstract
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, R 1 are identical or dissimilar monovalent saturated or unsaturated hydrocarbons with 1-30 carbon atoms, R 2 is a monovalent organic group represented by CR.sup.3.sub.2 CR.sup.3 (H)CR.sup.3.sub.2 --R.sup.3, R 3 are hydrogen atoms or monovalent saturated hydrocarbon groups with 1-5 carbon atoms. R 4 are monovalent organic groups represented by the formula: ##STR1## R 5 being identical to said R 1 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.
