Abstract: | Glassification, cast polymerization, and physical properties of monomeric system including diethylene-glycolbisallyl carbonate (CR-39) was investigated. Addition of other monomers CR-39 was investigated CR39- polyfunctional monomer and CR-39-methyl methacrylate-polyfunctional monomer systems were found to form stable glassy state applicable to radiation-induced casting and good in physical property. Two-step polymerization method consisting of pre-irradiation and post-catalytic polymerization necessary to complete casting. It was found that these newly found CR-39 modified systems could be casted efficiently in much shorter time cycle than catalytic process without forming optical strain. Physical properties of casted polymer such as impact resistance and heat durability were sufficient for practical use. |
