Abstract
Abstract
Butyl rubber vulcanized with 2,6-dimethylol-4-hydrocarbylphenols or condensation polymers derived therefrom shows exceptional thermal stability. This offers a means of obtaining economical and highly heat resistant vulcanizates. Vulcanizates prepared in this manner resist aging from four to ten times as well as do vulcanizates prepared with sulfur and sulfur vulcanization accelerators. It is estimated that the upper temperature limit of serviceability of butyl rubber may be increased by 100° F through the use of this vulcanization system.
