Abstract
The present invention relates to a mononitrone of the formula: ##STR1## The amount of alpha-(2,4-dihydroxy)phenyl N-phenyl nitrone which is used in the modification of a diene containing polymer may range from about 0.1 to about 30 percent by weight of said polymer. The modified polymers exhibit improved tear properties as measured by Strebler adhesion values.
