Abstract


Acrylonitrile was copolymerized with 8-methacryloxy-quinoline in Dimethylformamide using azobisisobutyronitrile as initiator. The composition of the copolymers was determined by nitrogen analysis and the monomer reactivity ratios (r1 and r2) were calculated. Both the homopolymer and the copolymers was characterized by a variety of spectral and thermal methods. Thermogravimetry and differential thermal analysis data showed that the comonomer (MAQ) initiates the nitrile oligomerization reaction in the copolymer upon heating. A mechanism for the initiation of (MAQ) units in the nitrile copolymers was also proposed.
