HNBR latex

The available studies indicate that diimide has been used as a reducing agent for the preparation of HNBR. It has been used mainly as an alternative for hydrogenation of nitrile rubber latex. The use of diimide to hydrogenate low-molecular weight olefines is well known in the organic literature [93]. Diimide can be conveniently generated in situ by thermal treatment of solutions of p-tolu-enesulfonyl hydrazide or oxidation of hydrazine. 

Butane is dehydrogenated into butadiene, which is used to synthesize SBR, BR, ENB (as the third monomer for EPDM), NBR, HNBR, CR, SBVP latex, SBS and SEES thermoplastic elastomer, ENB (for EPDM to be blended for use with polypropylene as a TPV), NBR/PVC fluxed masterbatch, and NBR (for NBR/PP TPV).
