Organic silicone compounds with aminoic acid moiety, organic silicone polymers with amide moiety, and preparing method thereof

摘要

PURPOSE: An amino acid organic silicon compound, an organic silicon polymer with an amide moiety, and a method for preparing the same are provided to obtain the organic silicon polymer containing the amide moiety with excellent adhesion to metal surface. CONSTITUTION: An amino acid organic silicon compound is prepared by esterification and amidation of a solution containing a silicon tetrachloride compound of chemical formula 1, an organic acid of chemical formula 2, and a diamine compound of chemical formula 3, and an organic solvent. The amino acid organic silicon compound is denoted by chemical formula 4, 5, or 6. A method for preparing the amino acid organic silicon compound comprises: a step of mixing the silicon tetrachloride compound of chemical formula 1 with water-diluted organic solvent and homogenizing the compound; a step of adding organic acid of chemical formula 2 and diamine compound of chemical formula 3; and a step of stirring the mixture in a water bath.
