Summary
-
1.
α, ω-Dihydroxydimethyldiphenyldisiloxane and someα,ω-dihydroxypolydimethylsiloxanes were reacted with methyltrichlorosilane and phenyltrichlorosilane to give the previously unknown trifunctional oligomers (I), (II), (III) and (IV) (see table), containing hydroxyl groups at the branch ends.
-
2.
Some of the properties of these compounds were studied.
