摘要
A process for the preparation of a sealant composition by mixing an elastomer in the substantial absence of an organic solvent and separately dispersing a quinoid curing agent in a polymer having a molecular weight below about 5,000 to form a curing agent concentrate. Thereafter, combining the curing agent concentrate with the elastomer to form the sealant composition. The composition is a rubber masterbatch having many applications and is advantageously, substantially free from organic solvents.
