Aminoalkylesteralkylpolysiloxanes

Abstract

Abstract TO PRODUCE A COPOLYMER CONTAINING (R-)A-SI(-C(-R'')2-CH(-R'')-(C(-R'')2)B-COO-(C(-R'')2)C-Z)- O((3-A)/2) UNITS AND -O-(SI(-CH3)2-O)D- HO-(SI(-CH3)2-O)D-H IS REACTED WITH A SILANOL STOPPED FLUID OF THE FORMULA, (C(-R'')2)C-CN (R-)A-SI(-X)(3-A)-C(-R'')2-CH(-R'')-(C(-R'')2)B-COO- (R-)A-SI(-X)(3-A)-H + CATALYST --> (R''-)2-C=C(-R'')-(C(-R'')2)B-COO-(C(-R'')2)C-CN + CATALYST --> (R''-)2-C=C(-R'')-(C(-R'')2)B-COOH + HO-(C(-R'')2)C-CN + ARE MADE BY THE FOLLOWING REACTIONS: (C(-R'')2)C-CN (R-)A-SI(-X)(3-A)-C(-R'')2-CH(-R'')-(C(-R'')2)B-COO- CYANOALKYLESTERALKYISILANES WITHIN THE SCOPE OF THE FORMULA: BLOCKS. IN THE ABOVE FORMULAS, R IS AN ORGANIC RADICAL, R'' IS AN ORGANIC RADICAL OR HYDROGEN, X IS A HYDROLYZABLE GROUP, Z IS A -CH2-NH2 OR A-CN RADICAL, A HAS A VALUE OF 0 TO 2, B HAS A VALUE OF 0 TO 4, C HAS A VALUE OF ONE TO 5, AND D HAS A VALUE OF 5 TO 500. THE COPOLYMER CONTAINING CYANOALKYLESTERALKYLSILANE UNITS IS USEFUL AS A SOLVENT RESISTANT PROTECTIVE COATING MATERIAL. THE COPOLYMER CONTAINING AMINOALKYLESTERALKYLSILANE UNITS IS THE PRIMARY INGREDIENT OF A DETERGENT RESISTANT CAR POLISH. AMINOALKYLESTERALKYLSILANES OF THE FORMULA: (R-)A-SI(-X)(3-A)-C(-R'')2-CH(-R'')-(C(-R'')2)B-COO- (C(-R'')2)C-CH2-NH2 ARE MADE BY HYDROGENATING THE CORRESPONDING NITRILE. A COMPOUND WITHIN THE SCOPE OF THE FORMULA, (R-)A-SI(-X)(3-A)-C(-R'')2-CH(-R'')-(C(-R'')2)B-COO- (C(-R'')2)C-Z
