    Notes: Abstract Structure formation in chlorosulfonated polyethylene films is described. Modification with phenol-formaldehyde resin leads to a change in the supermolecular structures, which are stabilized by introducing 1% aluminum diisobutoxymonoacetoacetate into the system. It is shown that modifying the chlorosulfonated polyethylene leads to the formation of stable supermolecular structures and a considerable improvement in the mechanical properties of the films.

    Notes: Abstract A demonstration is given of the possibility of using the thermomechanical characteristics (temperature dependence of strain in uniaxial tension) of polymer films in the low-temperature range as a rapid and sensitive method of estimating brittleness temperature. A description of the apparatus is given, together with experimental data on the variation of the brittleness temperature of PVC films as a function of the type and amount of plasticizer and filler, and in the aging process. These results illustrate the possibility of utilizing the method for estimating an important property — brittleness temperature — and studying the structural transformations that affect the temperature threshold of deformability of polymers.

    Notes: Abstract The temperature dependence of the stripping strength of adhesive joints between steel and dural plates using crystalline polymers as adhesive (mixed polyamide-4, 5, 8 and guttapercha, both unfilled and filled with an inert filler) has been investigated. The temperature-strength curves pass through two local maxima, near the glass transition temperature of the crystalline adhesive and near its melting point. It is shown that the presence of a high-temperature maximum is determined by recrystallization of the polymer in the overstressed zone at the tip of the developing crack. The relationship between temperature and strength in adhesive joints based on crystalline polymer adhesives is very pronounced in both cohesive and adhesive failure. It is shown that the addition of filler reduces the recrystallization stress of guttapercha.
