AMPHIPHILIC CO-NETWORKS, FILMS MADE FROM AMPHIPHILIC CO-NETWORKS AND USES FOR SUCH CO-NETWORKS AND FILMS

摘要

The present invention relates to the production of amphiphilic copolymernetworks or co-networks that are both hydrophobic and hydrophilic, thecopolymer networks comprise polyalkylene glycol segments and disubstitutedpolysiloxane segments. Furthermore, the present invention relates to productsand/or films made from the amphiphilic copolymer networks or co-networksproduced in accordance with the synthesis methods of the present invention. Inone embodiment, amphiphilic networks or co-networks are synthesized usingfunctional multiblock co-polymers according to the formula (AY)x(BY)y, where Arepresents an alkylene glycol polymer having n repeating alkylene glycolunits, B represents a disubstituted siloxane polymer having m repeatingsiloxane units, and Y represents a molecule (e.g., a silane) that functionsboth as a chain extender and a crosslinker.
