Ka. Job et al., MECHANICAL PROPERTY IMPROVEMENT OF NBR IIR BLENDS BY PARTIAL PRECURING OF IIR/, Kautschuk und Gummi, Kunststoffe, 46(4), 1993, pp. 290-292
Isobutylene-isoprene rubber (butyl rubber) and butadiene-acrylonitrile
rubber (nitrile rubber) blends have been prepared by precuring the sl
ow curing butyl phase and then blending it with NBR. The optimum amoun
t of precuring that has to be given in the butyl phase has been determ
ined. The blends prepared by this novel method have been found to poss
ess better mechanical properties compared to the corresponding convent
ional blends.
