摘要：

Based on a previous kinetic investigation of batch emulsion copolymerization of styrene-ethyl acrylate (EA), the paper deals with experimental investigation on the copolymer microstructure (sequence distribution) and glass transition temperature. The DSC and NMR data are compared to theoretical quantities derived from a simulation taking into account monomer partition and polymer characteristics. Agreement between experiment and theory is fairly good; in particular the effect of difference of reactivity ratios which results in a huge composition drift for EA rich feeds, inducing a complex glass transition behaviour, is well accounted for. Comparison between experimental and theoretical (simulation) data could give useful indications of polymer compatibility. © 1990.
