摘要:
By the use of special cross-linkers that contain at least two isocyanate groups, hydroxyl group-containing optionally hydrogenated nitrile rubber polymers can be successfully cross-linked. Preferred cross-linkers contain allophanate, biuret, uretdione, uretonimine, bridged carbamate, carbodiimide, isocyanurate, iminooxadiazinedione or oxadiazinetrione structural elements.
