| Abstract: | The composition of the poly(styrene sulfone)s formed were measured for comonomer liquid mixtures with Xst=0.1 0.9 at the temperature of 50°C. Copolymerization was initiated with AIBN as the initiator. The copolymer composition showed an increase with an increasing amount of comonomer. The copolymerization of styrene with sulfur dioxide to form a variable composition polysulfone with an average styrene:sulfur dioxide molar ratio n≥1.0 was also examined. The pen-penultimate modeling of copolymerization was used to account for the triad monomer sequence and composition of poly(styrene sulfone). It was found that the theoretical modeling of copolymerization can very effectively evaluate the triad monomer sequence and composition of poly(styrene sulfone). |
