RESEARCH OF PROPERTIES OF POLYMER MIXTURES OBTAINED THROUGH VARIOUS METHODS

The properties of polymer mixtures obtained by various methods in solid phase, solution and emulsion have been investigated. It has been shown that it is possible to obtain composite materials with different properties based on mixtures of polymers obtained in the solid phase as a result of thermal-mechanical effects. It has been determined that the addition of PVC of 5–10 k.h. leads to an increase in the unsaturation of the elastomers and the amount of chlorine combined in them. The increase in the reactivity of elastomers makes it possible to obtain compositions resistant to various effects based on them. Properties of mixtures obtained from separately diluted solutions with elastomers - SKEP-50 and SKEPT-60 and functional polymers - PVC and CAPP have been investigated. It has been shown that despite the absence of chemical bonding in such mixtures, physical bonding occurs in the resulting mixtures. As a result, it has been confirmed by various methods that there is combined chlorine in the mixtures and that a new structure is formed, different from the structure of the initial components. Emulsions of SKEP-50, SKEP-60 and PVC have been obtained and mixed. The physical-chemical properties of the mixture of emulsions and IR spectrum and stability of the polymer layer obtained from the mixtures have been investigated. It has been shown that, unlike emulsions of initial polymers, the emulsion mixture has high physical-chemical and durability properties and can be used as a protective coating
