Abstract
The dependence of Huggins constant k′ of dilute polyhexamethyleneguanidine hydrochloride solutions on the synthesis duration and monomer molar ratio is determined. It is established that a partially branched polymer is formed at even an equimolar ratio of the monomers, a result that is testified by the rise of k′ after 7 h synthesis from 0.35 to 0.80 in the absence of a rise in the characteristic viscosity.
