- Аннотация: A theory describing slow macromolecular reaction and interdiffusion in a compatible polymer blend is extended to consider H-bonding. The known treatments of H-bonding influence on the free energy of mixing and chains' mobilities are combined to calculate mutual diffusion coefficients in the framework of linear non-equilibrium thermodynamics. Numerical calculations are performed for a blend of two random copolymers AC and BC to reveal the effect of H-bonding (between A and B, B and B units) on the interdiffusion profiles. Then, the transformation of A units into B ones is included and the reaction-diffusion equations are solved with the parameters corresponding to the blend of poly(tert-butyl acrylate-co-styrene) with poly-(acrylic acid-co-styrene) in which the thermal decomposition of tert-butyl acrylate units takes place. The numerical calculations show that this system is suitable for the experimental verification of theoretical predictions concerning the interplay between macromolecular reaction and interdiffusion in polymer blends.
