Correlation of macroscopic properties of segmentem polyurethane and polyurethane-urea elastomers
and their structure. Part I. Dynamic hydroabrasive wear of linear elastomers
On the basis of literature data and own observations it has been assumed the discontinuity in the changes of macroscopic properties of segmented elastomers as a function of the content of rigid mers. The correctness of this hypothesis has been proved experimentally on the example of 4 series of segmented polyurethane and polyurethane-urea elastomers by investigating their dynamic hydroabrasive wear with the application of a specially elaborated procedure allowing for modelling the exploitation conditions of such elastomers. In these studies the existence of threshold values of the soft mer/rigid mer ratio has been observed; these values correspond with the abrupt changes in the dynamic hydroabrasive wear.
