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'').… more

Synthesis and self-assembly of fluorocarbon- and hydrocarbon-modified hydrophilic polymers. Final report

Description: Over the past 3 years, work was done in several areas: effect of spacer lengths on degree of association of hydrophobically modified polyacrylamides; fluorocarbon mediated association of R{sub F}- substituted polyacrylamide-2-(acrylamido)-2-methyl-propane sodium sulfonate copolymers; hydrophobic association in R{sub F}(R{sub H})-modified poly(N,N-dimethylacrylamide)(PDMA) and polyvinylpyrrolidone; synthesis of R{sub F}-containing poly(N- isopropyl acrylamide)`s; synthesis of HM narrow MWD telec… more
