GELS FROM POLYSTYRENE-BASED PHOTOINITIATORS

摘要

The invention provides a method for the manufacture of a gel precursor. The method comprising the steps of combining a polymeric photoinitiator of the general formula (I) : with one or more gel -forming polymers and/or gel -forming monomers to form a matrix composition, and curing the matrix composition obtained in the first step by exposing it to UV radiation. The invention also relates to the gel precursor itself, a method for the manufacture of a hydrophilic gel, the hydrophilic gel itself and a medical device comprising or coated with said gel.
