FUNCTIONAL METALLOSILOXANES, PRODUCTS OF THEIR PARTIAL HYDROLYSIS AND THEIR USE

摘要

The invention relates to the field of chemical technology of organic silicon compounds, in particular, to functional metallosiloxanes, products of their partial hydrolysis, the method of their preparation, and to their use as crosslinking agents in compositions based on rubber. Disclosed are functional metallosiloxanes of the general formula (I): wherein M is a two-, three-or four-valent metal; p+m correspond to the valence of the metal, provided that p and m ≠ 0; n is 0 or 1; R represents C1-C4 alkyl; R' and R" are independently the same or different and represent C1 -C4 alkyl, C6H5-, CH2=CH- and NH2(CH2)x, where x has a value from 2 to 5; and Alk is a C1-C4 alkyl substituent. Also disclosed is the method for preparing functional metallosiloxanes, products of their partial hydrolysis and the method of their preparation, and their use as crosslinkers in curable compositions based on rubber, preferably silicone rubber.
