摘要：

Polymers of ethylene glycol dimethacrylate, diethylene glycol dimethacrylate, triethylene glycol dimethacrylate and tetraethylene glycol dimethacrylate were produced by photopolymerization using the photoinitiator 2,2-dimethoxy-2-phenyl-acetophenone. These polymerization reactions and the resulting materials were examined as to their feasibility for production of laser video discs using the 2p process. The volume shrinkage during polymerization, swelling characteristics, molecular weight between crosslinks and the glass transition temperature of the polymeric networks were determined and compared with the characteristics of polymers presently used in laser video disc production. The networks produced by the polymerization of these monomers were highly crosslinked with glass transition temperatures greater than 200°C. They swelled little in any of four solvents used with a maximum volume fraction of the solvent at equilibrium lower than 10%. © 1990.
