Abstract
A method of crosslinking polymers containing unreacted olefinic groups at room temperature is disclosed. This process involves adding for each mole of olefin group present in the polymer three equivalents of a diisocyanate group-containing compound and one mole of nitromethane. This mixture forms in situ the acyl nitrile oxide group which then reacts with the olefin groups present in the polymer to effect a crosslinking reaction.
