    摘要： The invention relates to a water-insoluble hydrophilic polymer network comprising polyorganosiloxane polyoxyalkylene block copolymer moieties characterised that they are linked to each other through an organosilicon cross-linking moiety, provided that the cross-linking moiety forming the links between polyorganosiloxane polyoxyalkylene block copolymer moieties result from an addition reaction between cross-linking sites present on the polyorganosiloxane polyoxyalkylene block copolymer moieties prior to formation of the hydrophilic polymer network, selected from silicon-bonded hydrogen atoms and aliphatically unsaturated groups, and reactive groups present on the cross-linking moiety prior to formation of the hydrophilic polymer network. Also disclosed is a process for making the polymer network, and a curable composition able to be reacted into such polymer network.
