T. Tsuneka et al., MATRIX POLYMERIZATION OF ACRYLAMIDE INDUCED BY THE INTERACTION BETWEEN CARBONYL AND AMIDE GROUPS, Journal of macromolecular science. Pure and applied chemistry, A31(9), 1994, pp. 1169-1176
Polymerizations of acrylamide (AAm) in the presence of several homo- a
nd copolymers such as poly(methyl vinyl ketone) (poly-MVK) and poly(N-
vinylpyrrolidone) (poly-VPr), copoly(MVK-St), and copoly(VPr-St) were
carried out in tetrahydrofuran (THF) at 30-degrees-C without catalyst.
Similarly, the polymerizations of AAm in the presence of poly(methyl
methacrylate) were also carried out in THF at 40-degrees-C. The increa
sing concentration of these matrix polymers increased the polymerizabi
lity of AAm. Number-average molecular weight (MBAR(n)) of the resultin
g poly-AAm were close to the molecular weight (MBAR(n)) of the matrix
polymers. The polymerizability of N-methylacrylamide was lower than th
at of AAm, and N,N-dimethylacrylamide did not polymerize at all. From
these results it appeared that these matrix polymerizations proceeded
by the interaction between the carbonyl group in the matrix polymer an
d the amide group of the AAm monomer.
