Abstract
In this work a study on thermodynamics of polymer blends, based on pol y(methyl acrylate) (PMA) and poly(vinyl acetate) (PVAc), was carried o ut. Our foremost aim was to examine the molecular weight effect on pol ymer compatibility. The results confirm our hypothesis: the interactio n parameter, chi(12), varies abruptly in a very restricted molecular w eight range. In this way, it can be concluded that molecular weight, a s well as other parameters (i.e. lateral group hindrance, chain functi onalization, composition temperature and so on), influences greatly po lymer miscibility.
