  • METHOD FOR MANUFACTURING HYDROPHILIC SILICONE MACROMER
    Publication number: 20130172574
    Abstract: A method for manufacturing a hydrophilic silicone macromer is provided. A hydrosilylation between a Si—H bond of a polysiloxane and a C?C bond of a hydrophilic mononmer is performed by using a rhodium-containing catalyst to form the polysiloxane having a hydrophilic side chain having an amide group or a phosphoryl choline group. After performing an end-capping reaction, the hydrophilic silicone macromer is formed.
