DEVELOPMENT OF THE OBTAINING METHOD OF MONTMORILLONITE-POLYVINYLPYRROLIDONE MODIFIER FOR THE THERMOPLASTICS

A new method of montmorillonite intercalation by polyvinylpyrrolidone is described in
this work. The structure and thermophysical properties of the developed nanomodifier and the
components rational ratio were investigated. The effect of intercalated montmorillonite on
physico-mechanical properties of the mixture of polycaproamide and polypropylene was
determined. These composites are characterized by significantly higher values of hardness and
modulus of elasticity compared to the original PP.

Properties of Thermoplastic Polyurethanes Based on the Mixtures of Simple Oligoethers

The interrelation between structures and strength, deformation, rheological, and tribotechnical characteristics of thermoplastic polyurethanes based on oligoether blends has been studied. A notable change of properties over the whole concentration range was observed. The best compositions have been found.
