POLY(CYCLOSILOXANE) COMPOSITION AND SYNTHESIS

Title:

POLY(CYCLOSILOXANE) COMPOSITION AND SYNTHESIS

Document Type and Number:

WIPO Patent Application WO2003033561

Kind Code:

A3

Abstract:

A poly(cyclosiloxane) is synthesized by oxidation with water in the presence of a Pt catalyst, followed immediately by polycondensation of the Si-OH groups to form Si-O-Si linkages. Thus, pentamethylcyclopentasiloxane can be polymerized into poly(pentamethycyclopentasiloxane).
