Abstract

When gradient index rods (GI rods) were prepared by interfacial-gel copolymerization, the bulk polymerization caused serious shrinkage, which, in turn, resulted in inevitable defects. These defects in GI rods can be reduced by control of reaction conditions. Experimental results revealed that properly adjusting the reaction conditions such as concentrations of initiator, chain transfer agent, and/or temperature could reduce the viscosities of the reaction mixtures and could produce GI rods with a parabolic refractive index distribution.
