Abstract
SummaryThe hydrolysis of methylvinyldichlorosilane in a hydrochloric acid-isopropanol mixture gives an oil whose major components have been isolated and identified as methylvinylcyclosiloxanes with 4 to G silicon atoms in the molecule. The grafting of the sepiolite by methylvinyldichlorosilane in a hydrochloric acid-isopropanol mixture results in a vinylic derivative of the mineral. The kinetics of the reaction shows that both the silane and its hydrolysis products are grafted. Furthermore, other cyclosiloxanes can be grafted on different minerals; for example, octamethylcyclotetrasiloxane has been grafted on chrysotile fibers, giving a methylated derivative.ZusammenfassungEs werden die Graftpolymere des Silicates Sepiolith mit Methylvinyldichlorosilan untersucht.
