The peculiarities of modifying polyamide 66/6 and polystyrene thermoplastics with polyvinylpyrrolidone in the viscous state have been studied. By applying in-strumental methods, the changes in morphology and phase transitions of modified materials have been revealed. The influence of the modifier on the strength and thermo-physical properties of the researched thermoplastics was determined.
Technological features of obtaining biodegradable binary blends of polylactide with polyhydroxybutyrate, polycaprolactone, thermoplastic starch, polybutylene adipate-co-terephthalate, polybutylene succinate, polybutylene succinate-co-adipate are considered. The influence of polymer applications on physical-mechanical, thermophysical, technological properties and ability to biodegradation and biocompatibility of the obtained materials is revealed. The main possible directions of using binary biodegradable polylactide blends are considered.
The regularities of the thermodynamic compatibility of various industrially produced polyolefins and heterochain polymers and the possibility of obtaining composite materials based on their mixtures with significantly increased performance properties based on existing production facilities and process equipment have been identified.
