Abstract
Copolymers of N-acryloyl-N'-methylpiperazine (AcrNMP) and methyl metha crylate (MMA) were synthesized in 1,4-dioxane using benzoyl peroxide a s initiator at 70 +/- 1 degrees C. The copolymers were analyzed by FTI R spectroscopy. The monomer reactivity ratios were determined by the m ethods of Fineman-Ross (F-R) and Kelen-Tudos (K-T), yielding the resul ts r(1) (AcrNMP) = 0.552 and r(2) (MMA) = 1.074 by the F-R method and r(1) = 0.466 and r(2) = 0.980 by the K-T method. The latter r values i n turn yielded Q = 0.56 and e = -0.49 for AcrNMP. (C) 1997 Elsevier Sc ience Ltd.
