Cationic copolymerization of cholesterol vinyl ether with N-allenylpyrrolidone yielded co-oligomers with molecular mass of 1200-2100. The polymerization of N-allenylpyrrolidone involves both 1,2- and 2,3-positions of the allenyl substituent to give four types of units as a result of prototropic isomerization of the initially formed structures. In the developed method, the composition of co-oligomers can be controlled and, hence, their hydrophilic/hydrophobic balance, solubility, and membranotropic properties can also be controlled to change the potential biological activity of the products.

AbstractThe copolymerization of isobutyl vinyl ether (IBVE) with methyl vinyl ether (MVE), initiated by the system 1,1-diethoxyethane/trimethylsilyl iodide/zinc iodide and conducted at 0°C in toluene, was found to be ‘living’ just as the homopolymerizations of these monomers. Monomer reactivity ratios are rIBVE = 1.08 and rMVE = 0.43. The lower critical solution temperature of polyMVE in water, situated around 37°C, was lowered to 10°C (for a 0.25 wt.-% solution) when 6 mol-% of IBVE units were introduced in copolymers of molar mass 3000 - 7000 g/mol. At higher IBVE contents, the polymers are insoluble in water at all temperatures.
