Abstract

In the present paper, we report the synthesis of a new amino polymer made of oxazolidinone using an efficient ecocatalyst called Maghnite-H⁺. The synthesis process contains two steps: the first consists to the preparation of an amino oxiran 3-(oxiran-ylmethyl) oxazolidin- 2-one (OMO) by a substitution reaction of epichlorhydrin by 2-oxazolidinone, the second step concerns a green polymerization of the resultant oxiran by a ring opening reaction catalysed by Maghnite-H⁺. The polymer have been successfully prepared and characterized by various techniques, such as ¹H NMR, ¹³C NMR, IR, which were used to elucidate the structural characteristics of the resulting polymers. The effects of the amount of Maghnite-H⁺ and temperature on the conversion and number average molecular weight of polymers were studied. The polymerization conversion and number average molecular weight, increased as the proportions of catalyst were increased.
