ABSTRACT:
A butadiene polymer composition containing a phenolic compound represented by the formula: ##STR1## wherein R.sub.1 is an alkyl having 1 to 4 carbon atoms, R.sub.2 and R.sub.3 are each independently a group represented by --C(CH.sub.3).sub.2 --R' in which R' is an alkyl having 1 to 5 carbon atoms or phenyl, and R.sub.4 is hydrogen or methyl, and a phosphorus-containing compound represented by the formula: ##STR2## wherein R.sub.5 and R.sub.6 are each independently an alkyl having 1 to 9 carbon atoms.
The composition is stable against the thermal deterioration and discoloration in the absence of oxygen as well as against the exposure to oxides of nitrogen gas.
