The effect of hard segments structure on the functional properties of polyurethane elastomers based on oligoesterurethane epoxides

A series of polyurethane elastomers based on polyester urethane epoxy oligomers and cycloaliphatic diamines was synthesized. The relationship of the physico-mechanical properties of these elastomers with the structure of their polymer chain was studied. It was established that various options for in...

Summary:A series of polyurethane elastomers based on polyester urethane epoxy oligomers and cycloaliphatic diamines was synthesized. The relationship of the physico-mechanical properties of these elastomers with the structure of their polymer chain was studied. It was established that various options for increasing the strength of the final elastomers can be implemented, depending on the type of initial oligoesters and diamines. They may be associated with an increase in the degree of microphase separation between hard and soft polymer segments, and with partial crystallization of soft segments as well.
