Abstract: A process for activating a hydroalkylation catalyst in a first state comprising an acid component and a hydrogenating metal component, including: (i) treatment at a temperature of at least 120° C. in the presence of hydrogen for a first duration to produce a catalyst in a second state having a first hydroalkylation activity; (ii) contacting the catalyst in the second state with an aromatic compound and hydrogen under a hydroalkylation condition effective to convert at least part of the aromatic compound to a cycloalkylaromatic compound and produce a catalyst in a third state; and (iii) treating the catalyst in the third state at a temperature of at least 160° C. in the presence of hydrogen but advantageously in the substantial absence of the aromatic compound for a third duration to produce an activated catalyst in a fourth state having a third hydroalkylation activity greater than the first hydroalkylation activity.

Abstract: Elastomeric compositions comprising propylene-ethylene-diene terpolymer based polyolefin additives useful in tire tread compositions. The elastomeric compositions comprise 100 phr (parts by weight per hundred parts of total elastomer) diene elastomers; about 0 to about 80 phr of processing oil; 0 to about 80 phr of a hydrocarbon resin; about 60 to about 140 phr of filler; a curative agent; and about 5 to about 30 phr of a silane functionalized propylene-ethylene-diene terpolymer. The silane functionalized propylene-ethylene-diene terpolymer comprises from about 2 wt. % to about 40 wt. % of ethylene and/or C4-C20 α-olefins derived units, from 0.5 to 10 wt % of diene derived units, and a silane coupling agent. The present elastomeric compositions are useful as tire tread compositions for improved tire performance.
