2-Pyrimidyl acrylamide (2PA) monomer was prepared by the reaction of 2-aminopyrimidine with acryloyl chloride. Its structure was confirmed by IR, 'H NMR, and MS spectroscopy. Binary copolymerizations of this new monomer with methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BuA), methyl methacrylate (MMA), vinyl acetate (VA), and acrylonitrile (AN) were performed in tetrahydrofuran, using 1 mol% azobisisobutyronitrile as initiator at 65°C. N analysis and 'H NMR spectroscopy were used to determine the composition of the copolymers. Copolymerization parameters for each system were calculated by both the Fineman & Ross and Kelen & Tudos methods. The monomer reactivity ratios for the systems 2PA-MA, 2PA-EA, ~PA-BuA, 2PA-MMA, 2PA-VA, and 2PA-AN were found by the Kelen & Tudos method to be rl = 0.58 f 0.042, r2 = 1.26 f 0-086; rl = 0.63 f 0.041, r2 = 1.04 0.072; rl = 0.88 f 0.051, r2 = 0.99 f 0.069; rl = 0.43 f 0.021, r2 = 1.60 f 0.094, rl = 0.69 f 0.051, r2 = 0-084 f 0.088; and r1 = 0.065 f 0.008, r2 = 2.54 f 0.220, respectively. The average Q and e values for 2PA were found to be 0.51 and 0.66, respectively.

The copolymerization of acrylonitrile (AN) with glycidyl methacrylate (GMA) has been investigated in tetrahydrofuran (THF). The reactivity ratios were estimated and the thermal behaviour of the homo-as well as the copolymers, both in air, and under nitrogen atmosphere was investigated using differential thermal analysis (DTA) and thermogravimetry (TG) techniques. GMA was found to initiate the nitrile oligomerization reaction in the copolymers upon heating. The dyeing ability, as well as the colour fastness towards UV light have also been investigated. It was found that the copolymers showed better affinity towards basic dyes compared to homopolyacrylonitrile. This affinity increases with increasing the GMA content in the copolymer.

Verglichen mit Homopolyacrylnitril zeigen die Copolymeren bessere Affinittit gegen basische Farbstoffe. Diese Affinitiit steigt mit zunehmendem GMA-Anteil im Copolymeren an.

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 (r 1 and r 2 ) 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.
