from o-tolylenediamine and propylene oxide by the GPC-method

It has been attempted to determine the course of the addition reaction of propylene oxide to o-tolylenediamine by means of separating the adducts by the GPC-method. It has been stated that the introducion of 1—4 moles of propylene oxide per 1 mole of o-tolylenediamine causes the addition reaction. At higher ratios of propylene oxide, namely 5—6 moles per 1 mole of amine, the polyaddition reaction takes place with the formation of polyether chains.
