摘要：
The formation of a polyelectrolyte complex between heparin (Hep) and aminoacetalized poly(vinyl alcohol) (PVAA) in aqueous media has been studied by measurements of turbidity, metachromasy, and induced circular dichroism. Three results were noted: (a) the Hep—PVAA complex in aqueous system is either in a state of liquid-solid equilibrium, or a homogeneous solution, according to the mixing conditions; (b) the reaction between Hep and PVAA was not perfectly stoichiometric; (c) the ordered structure of Hep was disordered by the formation of complex at low pH. © 1978, The Society of Polymer Science, Japan.
