The light-focusing plastic rod (LFR) and fiber (LFF) were fabricated by photocopolymerization of methyl methacrylate (MMA) with vinyl phenylacetate (VPAc). The MMA-VPAc LFR has much higher clarity than that of the MMA-vinyl benzoate LFR reported previously. Using the benzoin methyl ether as the initiator, which initiates photopolymerization preferentially, led to a much steeper index distribution than using benzoyl peroxide, which initiates thermal- and photochemical polymerization simultaneously. The relationships between preparation condition and optical characteristics were clarified in terms of the index distribution, light scattering, lens function, and attenuation of light transmission.
