Abstract
A process for polymerization of diethylene glycol bis allyl carbonate which may advantageously be employed for producing plastic lenses having a low refractive index comprising in the step of subjecting diethylene glycol bis allyl carbonate to the step of gamma radiation in the presence of diiso propyl peroxydicarbonate as a catalyst.
Claims4
A method for polymerization of diethylene glycol bis(allyl carbonate) consisting essentially of irradiating diethylene glycol bis(allyl carbonate) monomer with gamma radiation in the presence of diisopropyl peroxydicarbonate as a catalyst.
A method for polymerization of diethylene glycol bis(allyl carbonate) comprising irradiating diethylene glycol bis(allyl carbonate) monomer with gamma radiation in the presence of diisopropyl peroxydicarbonate as a catalyst, wherein the radiation is carried out for a period of 8 to 10 hours.
