  • Polymer networks, process for producing same, and products made therefrom
    Patent number: 8258200
    Abstract: The present invention relates to the production of copolymer networks, or co-networks, and to methods for preparing copolymer or co-networks. Furthermore, the present invention relates to products and/or films made from the copolymer and/or co-networks produced in accordance with the synthesis methods of the present invention. Additionally, the present invention relates to crosslinked copolymer and/or co-networks comprising at least one hydrophilic segment and at least one hydrophobic segment. In one embodiment, the hydrophilic segments include at least one poly(vinyl alcohol) (e.g., a poly(vinyl alcohol) modified with acryl amide groups) and the hydrophobic segments include at least one polysiloxane having at least one terminal —OH group (e.g., polydimethylsiloxane (PDMS)). In another embodiment, the copolymer and/or co-networks of the present invention are optically clear and highly oxophilic.
