DEPENDENCE OF WET SKID RESISTANCE UPON MOLECULAR STRUCTURE

A hypothesis has been proposed linking the wet skid resistance (WSR) of elastomers with the monomeric friction coefficient (MFC), which is indicative of polymer chain mobility, and molecular weight between molecular entanglements (Me) using the Rouse theory of viscoelasticity. It has been shown that the relationship between these parameters and WSR is much better compared to that between WSR and glass transition temperature. Using the Rouse H theory, the wet skid ranking of several elastomers (at 25 degrees centigrade) has been successfully predicted. Calculations at 100 degrees centigrade suggest that the wet skid behavior may be qualitatively and quantitatively different at this temperature. This study indicates that MFC and Me strongly influence the WSR, with the glass transition temperature perhaps exerting a minor influence. (A)
