- NOVEL MONO-SYNTHESIZABLE SPONTANEOUSLY WATER-SOLUBLE SUBSTANTIALLY VOC-FREE ENVIRONMENTALLY FRIENDLY METHACRYLAMIDO-FUNCTIONAL SILOXANOL SYSTEMS PROCESS FOR THEIR PREPARATION AND USE

摘要

The present invention relates to compositions comprising substantially water-soluble (meth) acrylamido-functional siloxanol and processes for their preparation and their use. The composition contains an acrylamido-functional siloxane oligomer obtained by reacting an aminoalkyl-functionalized silicon compound (or a hydrolysis product resulting from the addition of water) with acrylic acid anhydride. Typical starting materials are 3-aminopropyltrimethoxysilane, 3-aminopropyltriethoxysilane, 3-aminopropylmethyldimethoxysilane, 3-aminopropylmethyldiethoxysilane, 1-aminomethyltrimethoxysilane, and the like . The product of the process can ideally be described by the following formula: (V) ^{(R 1 O) [(R} 1 O) 1-a (R 2) a Si (C) 1+ b O] u [(Y) Si (C) 1+ b O] u ' R ¹ (HX) _z Wherein, - C is the corresponding even-acrylamido groups and, - Y corresponds to OR ¹ or O _1/2, and, - R ¹ is hydrogen and R ² is an alkyl group, - HX is wherein X is an organic acid / inorganic acid radical It is an acid.
