dc.description.abstract | The thermal degradation of a series of 18 copolymers of 2-methylaziridine and 1-(2-hydroxyethyl)aziridine with N-phenylmaleimide and derivatives obtained without added catalyst, was investigated using thermogravimetry (TGA) under a dynamic nitrogen atmosphere over a temperature range from 20 to 500-degrees-C. Almost all the copolymers degrade in one step. The kinetic parameters E(a), n and A were obtained following one method of thermogravimetric analysis. The thermal stability depends on the copolymer composition which was determined from the H-1 NMR spectra. The most stable material was poly(p-nitrophenylmaleimide-co-2-methylaziridine). | |
