CROSS-LINKING AGENTS CONTAINING ISOCYANATE GROUPS FOR NITRILE RUBBERS

摘要

By using specific cross-linking agents which contain at least two isocyanate groups, optionally hydrated nitrile rubber terpolymers containing hydroxyl groups can be cross-linked successfully. Preferred cross-linking agents have allophanate, biuret, uretdione, uretoneimine, bridged carbamate, carbodiimide, isocyanurate, iminooxadiazindione or oxadiazintrione structural elements.
