Features of the thermodynamics of blending of semicrystalline polymers under the action of applied mechanical fields

Features of the thermodynamics of blending of isotactic PP and HDPE are ana lyzed on the basis of generalized experimental data obtained by the methods of elastic-strain action and plastic flow under high pressure. Effect of t he blending conditions (pressure and shear deformation) and molecular masse s of the components on the thermodynamic Gibbs potential is qualitatively e stimated in terms of the interaction between components.
