The photocopolymerization of methyl methacrylate (MMA) with vinyl benzoate (VB) containing benzoyl peroxide (BPO) was carried out in a glass tube to fabricate a light-focusing plastic rod (LFR, radius Rp) with a parabolic refractive-index distribution (distribution constant A) in the region near the center axis (radius Rc). The dependence of A and Rc/Rp on MMA/VB, BPO concentration and the velocity of the UV lamp was clarified. These relations could be explained using a computer simulation based on the polymerization mechanism.
