✦ Synopsis

The free radical copolymerizations of hydroxyethyl methacrylate and tetrahydrofurfuryl methacrylate have been investigated at 50°C. The compositions of polymers prepared at low conversions have been determined using 13 C-NMR, and the glass transition temperatures determined by DSC. The copolymerizations were found to be best described by a terminal model with reactivity ratios of r H ϭ 1.79 and r T ϭ 0.76. The triad fraction sequence distributions have been calculated based on the terminal model and the calculated reactivity ratios. The glass transitions have been fitted to the Gordon-Taylor equation. The best value of the Gordon-Taylor constant was found to be k H ϭ 1.42 Ϯ 0.2, indicating nonideal mixing of the two monomer components in the copolymers.
