Abstract
A method of desulfurizing sulfur-crosslinked rubber includes adding at least one selected from the group consisting of primary and secondary phosphine oxides and analogues of the primary and secondary phosphine oxides, primary and secondary phosphines which become oxides when oxidized and analogues of the primary and secondary phosphines, sulfenic acid, and sulfinic acid as a desulfurizing agent that acts on a sulfur bond in the sulfur-crosslinked rubber and cleaves the sulfur bond to the sulfur-crosslinked rubber, and performing heating.
