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.

标 题 :Synthesis of silyl ketene acetal from allyl 2-organoacrylates
发明人：REVIS ANTHONY
权利人:DOW CORNING
摘要:A process is described for preparing silyl ketene acetals having the formula, n n (CH.sub.3)RCâ•?C(OSiR.sup.i.sub.3).sub.2, n n from allyl 2-organoacrylates. The process comprises contacting an allyl 2-organoacrylate with a trisubstituted silane in the presence of a rhodium catalyst; and separating and isolating the silyl ketene acetal. Silyl ketene acetal of greater than 85-90 percent purity can be recovered.
