Adhesion and Energy Characteristics of Rigid-Chain Polymer Surface: Polyamidoimides by Anatoly E. Chalykh, Valentina Yu. Stepanenko, Ali D. Aliev

“…The adhesion characteristics and surface energies of two series of polyamidoimides (PAI) with different molecular weights, monomer unit structures, hinge groups in the main chain of the macromolecules, and thermal prehistory were determined via delamination at 180° and test fluids contact angles. …”

Water Sorption by Polyheteroarylenes by Anatoly E. Chalykh, Tatiana F. Petrova, Igor I. Ponomarev

“…Water mobile and cluster states depend on the structure of macromolecules and thermal prehistory of polymer sorbents. It is shown that the translational coefficients of water diffusion for all PHAs are in the range from 10⁻⁹ to 10⁻⁸ cm²/s. …”

The Energy Characteristics of the Surface of Statistical Copolymers by Anatoly E. Chalykh, Valentina Y. Stepanenko, Tatiana F. Petrova, Anna A. Shcherbina

“…The results of systematic studies on the surface energy <i>γ</i> and its polar <i>γ</i>^P and dispersion <i>γ</i>^D components of statistical copolymers of styrene and butadiene, acrylonitrile and butadiene, and butyl acrylate and vinyl acetate, with regard to their thermal prehistory, are generalized. Along with copolymers, the surfaces of their composing homopolymers were examined. …”
