发明名称 Unsaturated urea polysiloxanes
摘要 New styrene-functional polysiloxanes are described which are obtained by reaction of aminoalkyl functional polysiloxanes with styrene isocyanates. The styrene functional urea polysiloxanes have improved hydrolytic stability and are useful, either by themselves or in combination with copolymerizable comonomers, in UV- or heat curable biocompatible and oxygen permeable coatings, films or shaped articles, especially in form of oxygen permeable contact lenses.
