A series of block copolymers composed of a fixed length of an (ar-vinylbenzyl)trimethylammonium chloride (Q) block (the number average degree of polymerization of the Q block, DP n,Q =57) and varying lengths of an N,N-dimethylvinylbenzylamine (A) block (the number average degrees of polymerization of the A blocks, DP n,A , ranging 11–50) were prepared by reversible addition-fragmentation...
A preliminary study on the direct controlled radical polymerization of a glycomonomer, namely 2-methacryloxyethyl glucoside (MAGlu), under reversible addition-fragmentation chain transfer (RAFT) polymerization conditions in aqueous media has been conducted. This represents the first example detailing the direct polymerization of a sugar monomer via RAFT and, significantly, has been conducted without...
A novel carboxybetaine monomer, 4-(2-acrylamido-2-methylpropyldimethylammonio) butanoate (AMPDAB), has been synthesized and copolymerized with acrylamide in an aqueous NaBr solution. The feed ratio of AM (M 1 )/AMPDAB(M 2 ) was varied from 90/10 to 0/100 mol%. Low conversion samples were collected and copolymer compositions were determined with 13 C n.m.r. by integration...
Water soluble polyzwitterions have been synthesized by free radical copolymerization of acrylamide with the novel carboxybetaine monomer, 2-(2-acrylamido-2-methylpropyldimethylammonio) ethanoate (AMPDAE). Feed ratios of 10 to 100 mol% AMPDAE were employed to give the polyzwitterion series, DAEAM. Copolymer compositions of low conversion samples were determined from 13 C n.m.r. by integration...
Hydrophobically modified, water-soluble terpolymers based on maleic anhydride and ethyl vinyl ether were evaluated for their ability to act as a host for hydrophobic molecules in water. Alternating copolymers of maleic anhydride and ethyl vinyl ether were reacted with primary amines in organic solvent, then hydrolysed in a dilute aqueous base. This modification technique allows precise, stoichiometric...
