SYNTHESIS AND CHARACTERIZATION OF COPOLYMERS FROM ACRYLIC AND METHACRYLIC-ACID WITH 2-METHYLAZIRIDINE BY SPONTANEOUS COPOLYMERIZATION

2-Methylaziridine (MAz) as a nucleophilic monomer and acrylic acid (AA ) and methacrylic acid (MA), respectively, as electrophilic monomers w ere copolymerized in the absence of initiator at various feed ratios. Copolymers were characterized by elemental analysis, FT-IR and H-1-NMR spectroscopy. The monomer reactivity ratios were determined by the Fi neman-Ross and Kelen-Tudos methods. Values of r(1) and r(2) were found to be less than unity for MAz-AA, and MAz-MA, corresponding to random copolymers with the tendency to the alternance. For all the copolymer s the thermal decomposition with 10% weight loss is higher than 430 K. The reaction order for degradation of all copolymers was zero. The ki netic parameters of the decomposition were determined for all copolyme rs.
