Abstract:
A transparent gel is disclosed which has an interpenetrating polymer network of a copolymer containing a polysiloxane structure and a polycarbonate structure and a hydrophilic polymer obtained by polymerizing a hydrophilic monomer. The transparent gel is useful as a cultivation substrate, a container for storage and an ophthalmic material, comprising an easily synthesizable and purifiable silicon-containing resin, wherein a gel strength, transparency, oxygen permeability, birefringence and other characteristics are excellent.
