Regulation Features of Structure of Linear Block-Copolyurethane Composites of High Wear Resistance

The influence of the main structural parameters (molecular weight and hard blocks content) as well as methods of filling linear block-polyurethanes and their compositions on their strength, deformation, rheological and tribotechnical characteristics has been studied. A complex approach to produce polyurethane compositions of improved wear resistance has been suggested.
