Resumo

The two-step copolymerization of diethylene glycol bis(allyl carbonate) (CR-39) with methacrylic ester of fluorine containing alcohol (FMA), i.e., trifluoroethyl methacrylate (3FMA) and 1,1,3-trihydroperfluoropropyl methacrylate (4FMA), was carried out to prepare a light-focusing plastic rod. The relations between the preparation conditions and the optical characteristics of the resulting rods were considered in the following terms: (a) diffusibilities of CR-39 and FMA; (b) copolymerization of FMA with CR-39; (c) slower diffusion rate of 4FMA than that of 3FMA due to molecular size effect. Low chromatic aberration and the excellent imaging property of the CR-39-3FMA rod lens are also presented.
