Die Makromolekulare Chemie, 190 (11), pp. 2975-29810025-116Xhttps://hdl.handle.net/10016/26014Segunda parte disponible en: http://hdl.handle.net/10016/26015Upon 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 of the turbidity of different solutions of PVP and PMBI as a function of polymer concentration and PVP molecular weight. Viscosity measurements were also performed. The polycomplex is weak. Polycomplex particles are more compact and much larger than separated chains of polyacid and polybase. No definite stoichiometry is observed and a microgel-like structure is proposed.7application/pdfeng© Hüthig & Wepf Verlag, Basel, 1989© Wileyresearch articleMaterialesQuímicahttps://doi.org/10.1002/macp.1989.021901128open access2975112981Die Makromolekulare Chemie190AR/0000010932
