Predictions of Thermal Properties of the Polymer Blends in Use and in Processing

The computational model for evaluation of the compatibility of two polymers used for the manufacture of polymeric materials has been suggested. The situation that occurs when the full and partial compatibility of the polymers takes place is analyzed. A design scheme was tested on mixtures of polyethylene oxide and poly(methyl methacrylate), which are fully compatible, and also mixtures of polystyrene and polycarbonate that are partially compatible. Found a good agreement of the experimental and calculated data. A design scheme can be useful for engineers involved in the manufacture of blends to create building materials.
