SYNTHESIS AND STRUCTURE OF POLY[N-(2-HYDROXYETHYL)-ETHYLENEIMINE-co-3,4,5,6 - TETRAHYDROPHTHALIC ANHYDRIDE]

The spontaneous copolymerization reaction in acetonitrile at 35C by 48 h between N-(2-hydroxyethyl)ethyleneimine with 3,4,5,6-tetrahydrophthalic anhydride under different experimental conditions was studied. The yield and molecular weight ranged between 57 - 78 % and 8.5 - 9.1·103 respectively. The...
