Saitarly S. Development of filled polymer compositions with improved properties based on polypropylene and oligobutadienes

The thesis is devoted to the development of polymer compositions with improved properties based on polypropylene and oligobutadienes using fillers and modifiers of various types. The composition and technological scheme of filled polypropylene compositions are developed with the enhanceable indexes of impact strength and frost resistance with using as a modifier a new polyolefin elastomer. The influence of the mineral filler and polyolefin elastomer on the rheological properties of polypropylene compositions by the method of capillary viscosimetry, on their thermal stability and temperature characteristics of phase transitions by the methods of differential thermal analysis and differential thermal gravimetry. Technological schemes for the preparation of compositions based on oligobutadienes for the preparation of coatings and sealants without the use of primers and adhesives, as well as ebonite protective coatings have been developed.
