Notes:
Amphiphilic oligomers of poly(N-acryloylmorpholine) terminated at one end by primary amino groups have been prepared by free radical polymerization of the corresponding monomer, N-acryloylmorpholine, in the presence of cysteamine (2-mercaptoethylamine) as chain-transfer agent. The polymerization reaction was performed in aqueous media at acidic pH, in order to avoid any hydrogen-transfer addition reaction the the acrylic double bonds by the SH or NH2 groups present in cysteamine. The chain-transfer constant of cysteamine towards N-acryloylmorpholine, under the conditions we used, was found to be very close to 1. The aminated poly(N-acryloylmorpholine) oligomers were found to behave as true macromonomers in polyaddition reactions with a diacrylamide, leading to new poly(amidoamines) carrying poly(N-acryloylmorpholine) chains as side substituents.
