Dependence of Wet Skid Resistance upon the Entanglement Density and Chain Mobility according to the Rouse Theory of Viscoelasticity

Abstract

Abstract Starting with the Rouse theory of viscoelasticity, the Theological behavior can be modeled in the transition zone. The predictions of the model are in qualitative agreement with both the experimentally obtained data in the transition zone and with the wet skid behavior of elastomers. Based upon the linear viscoelastic spectrum for amorphous polymers, the wet skid resistance of elastomers can be related to the chain flexibility. The Rouse mechanism is able to explain the wet skid results qualitatively for most of the commonly used elastomers, including IIR. This study establishes that transition region motions are influential in determining the wet skid behavior of an elastomer, with the glass transition temperature itself perhaps playing a minor role.
