Title: Radiation polymerization method of biocompatible and hydrophilic silicone-containing monomer and hydrophilic monomer
Inventor: YOON JAE MAN
IPC: C08F2/46
Filed: 2021-01-06
Granted: 2021-09-02
Abstract: The present invention relates to a method for polymerization of hydrophobic silicone with a hydrophilic monomer. Particularly, the present invention relates to a method for radiation polymerization of a highly biocompatible and hydrophilic silicone-containing monomer with a hydrophilic monomer. The method includes the steps of: mixing a hydrophobic silicone monomer with a hydrophilic monomer; and irradiating radiation to the resultant mixture to carry out polymerization into an interpenetrating polymer network (IPN) structure having both advantages of hydrophobicity and hydrophilicity. The method for radiation polymerization of a highly biocompatible and hydrophilic silicone-containing monomer with a hydrophilic monomer according to the present invention uses 2-methacryloyloxyethyl phosphorylcholine (MPC) as a hydrophilic monomer, and thus advantageously prevents surface adhesion of protein, provides anti-fouling property and high human compatibility and realizes advantages of both hydrophilic and hydrophobic monomers through the polymerization with a hydrophobic silicone monomer. In addition, the radiation polymerization method, not a chemical method (crosslinking agent addition), can minimize a complicate process and purification process, requires no step of removing unreacted reactants, such as additives, used in general chemical polymerization methods, and eliminates the problem of a difficulty in removing unreacted reactants completely.
