| Abstract: | The PMMA macromer was obtained by radical polymerization in the presence of 2-mercaptoethanol as a chain transfer agent, followed by termination with acryloyl chloride. The structure of PMMA macromer was characterizaed by means of IR, 1HNMR.The effects of various polymerization conditions, such as amout of initiator,kinds of solvent, concentration, and polymerization temperature on the yield of PMMA-OH were investigated. |
