Ie. Serhatli et al., Synthesis and characterization of N-phenylmaleimide-methylvinylisocyanate copolymers with polystyrene side chains, POLYM BULL, 44(3), 2000, pp. 261-268
N-Substitued maleimide-methylvinylisocyanate copolymers with high glass tra
nsition temperature (T-g) was prepared and reacted with 4-hydroxy TEMPO (4-
hydroxy-2,2,6,6-tetramethyl piperidinoxy) to yield polymers possessing stab
le radical at the side chain. The resulting polymers behaved as polymeric c
ounter radicals for the radical polymerization of styrene. Thus, stable fre
e radical mediated polymerization at the side chain was achieved. The resul
ting graft copolymers were characterized by spectral and thermal analysis.
