| Description |
n-Dodecyl acrylate (DA) and dodecyl-4-vinyl benzoate (DVB) were copolymerized
by conventional free-radical polymerization (CFRP); atom transfer radical
polymerization (ATRP), and nitroxide-mediated living free-radical polymerization
(NMLFRP) with benzoyl peroxide, 1-phenyl ethyl chloride/cuprous chloride/2,2 -bipyridine,
and benzoyl peroxide/2,2,6,6-tetramethylpiperidinyl-1-oxy initiator systems, respectively.
In CFRP and NMLFRP, toluene and xylene were used as solvents, whereas
ATRP was performed in bulk. Mayo–Lewis, Kelen–Tu¨do¨s, and Fineman–Ross methods
were used for the determination of the monomer reactivity ratios (r1 and r2). They all
gave nearly the same values of r1 and r2. The reactivity ratios of the two monomers in
CFRP, ATRP, and NMLFRP were 0.17 r1 0.4 (DA) and 1.0 r2 1.24 (DVB). The
side-chain crystallinity of the copolymers decreased with an increasing DVB molar
fraction. J Polym Sci Part A: Polym Chem 40: 1818–1830, 2002
