Abstract: front page image
(EN)The present technology provides compositions, methods, and processes to form polysiloxanes. In one aspect, the present technology provides a process for the ring opening polymerization of a cyclosiloxane comprising contacting a cyclosiloxane with a bicyclic guanidine compound. The guanidine-containing compounds useful in the ring opening reaction include a fused ring structure comprising a guanidine functional group as part of the fused ring.
(FR)La présente invention concerne des compositions, des procédés et des processus de formation de polysiloxanes. Dans un aspect, l'invention porte sur un procédé de polymérisation par ouverture de cycle d'un cyclosiloxane, comprenant la mise en contact d'un cyclosiloxane avec un composé de guanidine bicyclique. Les composés contenant de la guanidine utiles dans la réaction d'ouverture de cycle incluent une structure d'anneau fusionné qui comprend un groupe fonctionnel de guanidine faisant partie de l'anneau fusionné.
