Sažetak
N(p-phenoxy-phenyl)methacrylamide (PhOPhMAA) prepared by condenzation of methacrylic acid anhydride with p-phenoxy-phenylamine readily homopolymerizes and copolymerizes with styrene (St) in the presence of azobisisobutyronitryle as initiator. The copolymers prepared under different monomer-to-monomer ratios in the feed have random composition with an azeotropic point at ratio of 0.65 (St) to 0.35 (PhOPhMAA). Reactivity ratios determined by Kelen-Tudos method are (r1(St)=0.61, r2(PhOPhMAA)=0.55. Activation energy determined by Arrhenius method is 71.2 kJ/mol. Poly(PhOPhMAA) and poly(PhOPhMAA-co-St) are thermally stable up to 350 C under TGA conditions. Tg's and higher transition temperatures are within the thermally stable region.
