Abstract:

A calculation method for predicting compatibility of two polymers on blending isproposed. The method is based on the criterion of polymer solubility in organic solvents; thecriterion takes into account the chemical structure of both polymer and solvent, surface forces, andthe polymer-solvent intermolecular interaction energy. When two polymers are mixed together, one of them is regarded as a "solvent". The applicability of the method to fully compatible, partially compatible, and absolutely incompatible polymers is ****yzed. It is shown that the composition of microphases at microphase separation can be approximately calculated using the dynamic mechanical ****ysis (DMA).
