Abstract

The photochemical polymerization rates of isoprene, ethyl methacrylate, and of styrene in various aromatic solvents were measured. The average lifetimes of propagating radicals were measured by the rotating sector method. The polymerization rate constants, K~p~, were determined and compared with dipole moments (μ) and Hammett σ constants for the aromatic solvents. Linear correlations of log(k~p~/k~p, benzene~) vs. μ and σ were obtained.

Radical copolymerlzations of 2-acryloyloxyethyl diethyl phosphate (ADP) with methyl methacrylate (MMA) and with styrene were carried out under various conditions. The reactivity ratios were determined by the method of Fineman-Ross. Under a given set of conditions, the reactivity of the acrylate term
