METHOD OF ELONGATING A CHAIN OF ALPHA, OMEGA-DIHYDROXY-POLY(DIORGANOSILOXANES), AND CROSSLINKABLE MIXTURE CONTAINING ALPHA, OMEGA-DIHYDROXY-POLY(DIORGANOSILOXANES) WITH SUCH ELONGATED CHAIN

摘要

The present invention relates to a process for extending the chain of {alpha}, omega-dihydroxy-poly(diorganosiloxane), wherein a low-molecular {alpha}, omega-dihydroxy-poly(diorganosiloxane) reacts with at least one phosphoric and/or orthophosphoric acid ester. In the present invention there are further described cross-linkable mixtures containing such {alpha}, omega-dihydroxy-poly(diorganosiloxanes) having elongated chain as well as use of the prepared {alpha}, omega-dihydroxy-poly(diorganosiloxanes).
