摘要：

The process of stereocomplexation between isotactic and syndiotactic PMMA in dilute solution was studied by means of differential scanning calorimetry of isolated complexed material, solution viscometry, and isothermal mixing calorimetry. The results were combined with results of investigations previously published. It appeared that essentially the same mechanism as proposed for the complexation process in bulk can account for the observed phenomena, including the previously reported association and aggregation stages following complexation. Two main processes are distinguished: complexation and subsequent crystallization of complexed chain sections, leading to the formation of complex particles.
