A hydrophilic polymer product obtained material made on the basis of the (lacuna) silicone crosslinked include in bound photoinitiators, their preparation, from the material, its manufacturing method, and the novel photoinitiators

摘要

(57) silicone crosslinked polymer based on the material that includes a silicone polymer matrix was [summary] cross-linking, the light start group bonded diffuse into the matrix. Use of this material in the production process for the purpose of making a hydrophilic substance which greatly simplified the production process, and the product of the result has the interesting and particularly advantageous feature. The present invention is useful in the manufacture of contact lenses.
