Abstract
The present invention relates to a rubber stock for bead wire compounds comprising (A) based on 100 parts by weight of rubber (1) from about 5 to about 40 weight percent of a carboxylated acrylonitrile-diene rubber having an acrylonitrile content ranging from about 15 to 45 percent by weight; and (2) from about 60 to about 95 weight percent of a non-carboxylated rubber selected from the group consisting of natural rubber, polyisoprene, polybutadiene, styrene-butadiene rubber, styrene-isoprene-butadiene rubber, styrene-isoprene rubber, isoprene-butadiene rubber and mixtures thereof; (B) from about 0.1 to about 10 phr of a methylene acceptor; and (C) from about 0.1 to about 10 phr of a methylene donor.
