Polythiol accelerated radiation cross-linking of olefinically unsaturated polymers

摘要

Improved radiation vulcanization of elastomers is accomplished by incorporating into the elastomer composition a polythiol. The polythiol is preferably a hydrocarbon thioether thiol and is normally liquid at room temperature with a molecular weight of at least 150. Though difunctional polythiols are operative in this invention, the preferred polythiols have about three to about five thiol groups per molecule.
