Preparation and Properties of Some Poly-aluminum Organosiloxanes with Cyclonetwork Structures

Abstract

Poly condensation of aluminum butoxide with α, ω -dihydroxydi-methylsiloxanes having varied polymerization coefficients has been studied. Some kinetic dependencies in the generation of cyclonetwork poly(aluminum dim ethylsiloxanes) have been investigated and the rate constants of cross-linking reaction, depending on the chain length of initial α, ω-dihydroxypolydimethylsiloxanes, have been calculated.
