Synthesis of novel associating water-soluble copolymers
Description:
Poly(N,N-dimethylacrylamide) (4 samples) and Poly(N-acryl-N- methylpiperazine) (10 samples) were prepared by anionic polymerization in THF at {minus}78{degrees} in the presence of Cs or coordinated Li counter cations. Molecular weights (SEC) range from 3800--250,000. The polymers are soluble in methanol, H{sub 2}O and chloroform and to a lesser extent, in THF and CH{sub 2}Cl{sub 2}. Molecular weight distributions were found to be fairly monodisperse (1.11 < D < 2.69). (See Proposed Research'').…
