摘要:The present invention relates to novel amine terminated cycloaliphatic polysiloxanes, and preparations thereof. More particularly, the invention provides several reaction schemes for the synthesis of amino-functionalized cyclo-aliphatic silicones and the products produced by the reaction schemes. In one embodiment of the invention, an amine functionalized silicone is prepared through a base-catalyzed ring-opening reaction. In another embodiment of the invention, an amine functionalized silicone is prepared through the hydrosilation of a silicone oligomer through the blocking and deblocking of an amine terminated in a vinyl group.

摘要:The invention provides compounds containing the ring-opening products of ethylenically unsaturated cyclic carbonates for use in preparing hydrogel polymers, as well as methods for their preparation. A preferred method of the invention includes the reaction of nucleophilic compounds containing Si, F, N or O atoms, or combinations thereof, or latent moieties in the form of unsaturated or hydroxylated functional groups, with ethylenically unsaturated glycerol carbonate derivatives. The compounds and hydrogel polymers are useful for the preparation of contact lenses.
