Abstract: Block copolymers comprising polyols and/or siloxanes and vinyl-thiocarbonate blocks can be made by reacting a thiocarbonate compound such as a dithio- or trithiocarbonate with generally any hydroxyl-terminated polysiloxane via an esterification reaction. The polysiloxane can have a very wide number average molecular weight range and can be chain extended and/or crosslinked as by using a polyisocyanate or a polycarboxylic acid. Desirably, vinyl compounds are then reacted in situ into the thiocarbonate to increase molecular weight thereof. The block copolymers can be used in personal care applications.
