Abstract
Effect of the chemical structure of urethane-containing elastomers on their abrasion resistance is studied. Dependence of the degree of volumetric wear on the hard segment content for the studied elastomers has a well-defined maximum. It is shown that polyurethanes and polyurethane ureas with a certain optimum content of hard segments exhibit the best abrasion resistance; this content depends on the chemical nature of oligomers used in synthesis.
