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.
