titleOfInvention |
Process for the preparation of hydroxyl-functionalized polyether-polysiloxane block copolymers |
abstract |
The present invention is directed to a hydroxyl-functionalized polyether-polysiloxane block copolymer of the structure A(-X—B) n n wherein: A represents said polysiloxane block;n B represents said polyether block; X is a linker group characterized by including the moiety Si—C—C— of which said Si is the terminal silicon atom of the polysiloxane block A; and, n is an integer of from 2 to 4,n nsaid block copolymer being further characterized by a terminal unsaturation of less than 0.04 meq/g, preferably less than 0.03 meq/g and more preferably less than 0.025 meq/g and the method for producing thereof. |
