Patent ID: 6943204

Claim:
A process for the surface modification of a silicone substrate, the process comprising the steps of: a. absorbing ethylene glycol dimethacrylate into silicone for between approximately 0.1 hours to 72 hours at a temperature of between approximately 0° C. and 100° C. in order to swell the silicone; b. removing the swollen silicone from the ethylene glycol dimethacryate; c. transferring the swollen silicone into an aqueous solution containing 2-aminoethyl methacrylate hydrochloride in a concentration of between approximately 0.1% and 50% and 2,2′-azobis(2-methylpropionamidine) dihydrochloride in a concentration of between approximately 0.1% and 10%; d. contacting the swollen silicone with the 2-aminoethyl methacrylate hydrochloride and the 2,2′-azobis(2-methylpropionamidine) dihydrochloride at a temperature of between approximately 30° C. and 80° C. for between approximately 0.1 hours and 24 hours; and e. removing the silicone from the aqueous solution.
