The polymerization of diethylene glycol bis(allyl carbonate) initiated by benzoyl peroxide has been studied at 85oc. The time dependence of conversion of double bonds has been monitored by near infrared spectroscopy and that of the radical concentration by electron spin rescnance spectroscopy. The d

## Abstract For the preparation of the lightβfocusing plastic rod (LFR) a gel rod of partially polymerized diethylene glycol bis(allyl carbonate) (CRβ39) was immersed in 2,2,3,3βtetrafluoropropyl methacrylate (4FMA) followed by heat treatment under nitrogen. Variations in the chemical composition i
A~aetiA pyrene end-labelled poly(bisphenol AF-diethylene glycol carbonate) has been synthesized. Its molecular weight and end-group composition were determined through a combination of u.v. absorption and fluorescence decay measurements of the pyrene end-groups. Through gel permeation chromatography
