摘要:
Block copolymers of recurring structural units of the series of polysiloxanes and recurring structural units of the series of aliphatic polyesters, polyethers or polyetheresters with rubber properties, the polymeric block-forming polymers in each case producing rubber-type products with glass transition temperatures below practical temperatures of use and a process for the production thereof.
