Abstract

The use of small amounts of plasticizers in the synthesis of polyurethane ureas allows for the production of cast materials with improved technological characteristics. Tributyl phosphate, diethylhexyl sebacate, and their mixture were used as plasticizers in amounts of up to 1.5 wt %. A positive effect on the physical and physicomechanical properties of elastomers based on 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate and the mixture of plasticizers was found.
