Complexation of poly(monobenzyl itaconate) and poly(N-vinyl-2-pyrrolidone) in dilute solution

摘要: Upon mixing dilute solutions (10−4 – 10−2 mol/l) of poly(monobenzyl itaconate) (PMBI) and poly(N-vinyl-2-pyrrolidone) (PVP) in methanol, soluble polycomplex particles are formed. Here we report on the spectrophotometric determination turbidity different PVP PMBI as a function polymer concentration molecular weight. Viscosity measurements were also performed. The is weak. Polycomplex more compact much larger than separated chains polyacid polybase. No definite stoichiometry observed microgel-like structure proposed.
