  • Patent number: 11339271
    Abstract: A crosslinking agent which is based on an aluminate complex salt of a hydroxyl group-containing organic compound, which crosslinks a carboxy group and a nitrile group. When the crosslinking agent is added to a carboxy group-denatured NBR latex, gloves having flexibility and a strength comparable to those of natural rubber gloves can be manufactured. Furthermore, the excellent creep resistance is a big characteristic. Moreover, unlike normal sulfur vulcanization gloves, the gloves do not contain sulfur and a vulcanization accelerator, and do not necessarily require addition of zinc oxide.
