1,3 Bis (Citraconimidamethyl)benzene (Perkalink 900) is an antireversion ag
ent, which is very effective in counteracting reversion in sulfur cured die
ne elastomers. The performance benefits of employing Perkalink 900 in IIR,
XIIR as well as NBR formulations have been demonstrated in the laboratory.
Mechanistic interpretation of the chemistry behind the crosslinking in IIR
and XIIR has been provided.
