Regulation of properties of mixes secondary thermoplastics polymeric additives.

Properties of polymeric compositions are investigated on the basis of mixes secondary polythene thermoplasts and polystyrene depending on structure of a mix. It is shown, that in the field of small additives of one of components of a mix on dependences of a breaking point, density, adhesive durability on shift to wood, superficial energy are observed their extreme increase that is connected to structural features of formation of compositions and interaction of components on border of the unit of phases. Influence of compatibilization polymeric additives is investigated: a copolymer ethylene with vinyl acetate, a copolymer of styrene with acrylonitril and thermoplastic polyurethane on physicomechanical and superficial properties of composites.
