Abstract:
1. A heat-treated elastomeric blend compound, comprising: a continuous phase comprising: a dispersed phase comprising: from 1% to 30% by weight, based on the total weight of the blend, of a hydrocarbon resin exhibiting an Mn of from 500 to 1000; and wherein said elastomeric blend compound has a haze % of 30 or less per 100 mil thickness; wherein said propylene based material has an isotactic propylene triad tacticity in the range of from 65 to 95% and a heat of fusion of from 5 J/g to 50 J/g as measured prior to blending with said crystalline polypropylene component, and the continuous elastomeric phase is crosslinked and envelops domains of the dispersed thermoplastic phase; and wherein the elastomeric blend compound is heated to at least the temperature at which 99% of the melting of the crystalline polypropylene component has occurred in a DSC thermogram during or subsequent to crosslinking of the compound.
