|1999 ||Ghi, PY, Hill, DJT and Whittaker, AK (1999) A study of the copolymerization of hydroxyethyl methacrylate and tetrahydrofurfuryl methacrylate. Journal of Polymer Science Part A - Polymer Chemistry, 37 19: 3730-3737.|
The free radical copolymerizations of hydroxyethyl methacrylate and tetrahydrofurfuryl methacrylate have been investigated at 50 degrees C. The compositions of polymers prepared at low conversions have been determined using C-13-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) = 1.79 and r(T) = 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) = 1.42 +/- 0.2, indicating nonideal mixing of the two monomer components in the copolymers. (C) 1999 John Wiley & Sons, Inc.
