Experimental study investigates the effects of component ratios on elastomer properties, indicating potential for enhanced mechanical performance.
The dependences of the properties of poly(urethane–urea) elastomers synthesized based on oligoethers and oligoesters (oligo(tetramethylene oxide) diol, oligo(diethylene adipate) diol) on the ratios between the components of the compositions are studied. It is found that the use of curing mixtures based on oligoesters in compositions based on oligoethers makes it possible to obtain poly(urethane–urea) elastomers with high hardness and excellent physical and mechanical characteristics. The boundaries of the temperature range of operation of the studied elastomers are discussed.
