実験手順

50 g of 2-phenyl-3-oxazoline are polymerized at the temperature of 150° C. for 40 minutes in the presence of an equimolar complex of perchloric acid with 2-phenyl-2-oxazoline taken in the ratio of the monomer to the initiator equal to 100:1. The resulting poly-N-benzoylethylenimine is hydrolyzed first with an aqueous solution of hydrochloric acid at reflux. The thus-prepared polymer is boiled in a solution of caustic soda. Linear polyethylenimine is dried over phosphorus pentoxide to give 12.8 g of an anhydrous polymer; the yield is 88%, intrinsic viscosity of the polymer [η]20 =0.18 dl/g (abs.alcohol) which corresponds to the molecular mass of 5,000.
