Abstract
Organosi1isium-polymerer med gjentagende si ly 1en-1,3-butadiyn og/eller disilylen-1,3-butadiyn-er.heter fremstilles i en én-beholders syntese fra heksaklorbutadien. Avhengig av de organiske substituenter (R og R') har disse polymerer anvendbare filmdannende egenskaper og omdannes til keramikk, som silisiumkarbid ved oppvarming i svert ensartede, høye masseutbytter. Polymerene kan ogsa strekkes til fibrer. Polymerene er termisk tverrbundet ved temperaturer over 100°C.Organosilicon polymers with repeating silylene-1,3-butadiene and / or disilylene-1,3-butadiene units are prepared in a single vessel synthesis from hexachlorobutadiene. Depending on the organic substituents (R and R '), these polymers have useful film-forming properties and are converted to ceramics, such as silicon carbide, by heating in very uniform, high mass yields. The polymers can also be stretched into fibers. The polymers are thermally crosslinked at temperatures above 100 ° C.
