Allophanate modified isocyanates which contain reactive unsaturation

摘要

This invention relates to a novel liquid, storage-stable diphenylmethane diisocyanate which contains allophanate and reactive unsaturation. These novel storage-stable liquids comprise the reaction product of diphenylmethane diisocyanate with an ethylenically unsaturated alcohol, in the presence of an allophanate catalyst and a suitable inhibitor.
