Abstract
Phenolic resin curatives having a majority of dibenzyl ether linkages were unexpectedly found to be very effective in curing unsaturated rubbers in a blend of a crystalline polyolefin and said rubber. Their effectiveness exceeds that of conventional phenolic resins for many thermoplastic vulcanizate compositions allowing for the reformulation of the recipes with lower amounts of curatives and equivalent or superior physical properties in the resulting thermoplastic vulcanizate.
