ABSTRACT:
The present invention relates to a sulfur vulcanized rubber composition containing 0.1 to 10.0 phr of an oligomeric maleimide of the formula: ##STR1## or a maleamic acid of the formula: ##STR2## wherein R and R.sup.1 are individually selected from the group of radicals consisting of hydrogen, an alkyl having 1 to 4 carbon atoms or a halogen; R.sup.2 is selected from the group of radicals consisting of 1 to 12 carbon atoms; X has a value of from 1 to 146 and n has a value of from 0 to 4.
The presence of the maleimide oligomer or maleamic acid improve cord adhesion to the sulfur vulcanized rubber compound.
