POLY(CYCLOSILOXANE) COMPOSITION AND SYNTHESIS
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). L'invention conce...

Summary: | 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).
L'invention concerne un poly(cyclosiloxane) synthétisé par oxydation à l'eau en présence d'un catalyseur Pt, suivie immédiatement par une polycondensation des groupes Si-OH afin de former des liaisons Si-O-Si. Ainsi, il est possible de polymériser un pentaméthylcyclopentasiloxane en un poly(pentaméthycyclopentasiloxane). |
