Abstract

Un procedimento per la produzione di organopolisilossani comprende lo stadio di mettere in contatto composti di organosilicio aventi almeno un'unità Ra Sio 4-a':2in cui R è idrogeno ossidrile, un gruppo, a C1 1-18', idrocarburico, idrocarburico sostituito od idrocarbonossi, a ha un valore da 0 a 4, con un alogenuro di fosfonitrile AB, in cui A è un catione di alogenuro di fosfonitrile [C(PX2=N)nPX3] ove X è alogenuro e n vale da 1 a 8, e B è un anione derivato da un acido di Lewis non contenente un atomo di P, ad es. [MX(v-t+l) R2t].Il procedimento è particolarmente utile per la condensazione di silossani ad estremità silanol-bloccata.
