POLYSILOXANE COMPOSITION WITH IMPROVED SURFACE WETTING CHARACTERISTICS AND BIOMEDICAL DEVICES MADE THEREOF

摘要

POLYSILOXANE COMPOSITION WITH IMPROVED SURFACE WETTING CHARACTERISTICS AND BIOMEDICAL DEVICES MADE THEREOF 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 N-alkenoyl aminates The improved polymeric compositions can be used to form hard, gas permeable contact lenses and other biomedical devices.
