| Abstract: | Urethane methacrylate macromer was prepared by reacting tolylene diisocynate(TDI) and polyethyleneglycol(PEG), followed by end capping with 2 hydroxyethyl methacrylate(HEMA) in the presence of dibutytin dilaurate(DBTL) as catalyst. The macromer polymerized with styrene(St) in the presence of free radical initiator to obtain a crosslinked transparent copolymer. The influence of several factors on the preparation of the macromer was studied. In addition, the curing behavior of the macromer with styrene was also investigated. |
