Abstract
Organosilicon compounds represented by the general formula: ##EQU1## and preparing process thereof were disclosed; where a lies in the range 1.ltoreq.a.ltoreq.3 and b lies in the range 0.001.ltoreq.b .ltoreq.2, PA1 R.sup.1 are identical or dissimilar monovalent saturated or unsaturated hydrocarbons with 1-30 carbon atoms, PA1 R.sup.2 is a monovalent organic group represented by EQU CR.sup.3.sub.2 CR.sup.3 (H)CR.sup.3.sub.2 --R.sup.3, PA1 R.sup.3 are hydrogen atoms or monovalent saturated hydrocarbon groups with 1-5 carbon atoms. PA1 R.sup.4 are monovalent organic groups represented by the formula: ##STR1## R.sup.5 being identical to said R.sup.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.
