ABSTRACT:
The surface wetting characteristics of polysiloxanes prepared from monomeric polysiloxanes endcapped with activated unsaturated groups and modulus modifiers are improved by the inclusion of small amounts of an N-alkenoyl trialkylsilyl aminate. The improved polymeric compositions can be used to form hard, gas permeable contact lenses and other biomedical devices.
