ABSTRACT:
In one aspect, the invention relates to silicon-based prepolymers. The disclosed prepolymers exhibit satisfactory solubility in aqueous solutions or hydrophilic solutions and can overcome undesirable shrinkage, expansion, and related problems possessed by conventional silicone monomers and related conventional polymerization techniques by producing hydrogels from a crosslinkable prepolymer. Also disclosed are polymers and molded articles produced from the disclosed prepolymers, which attain a satisfactory oxygen permeability. Also disclosed are methods for producing the disclosed prepolymers. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
