ABSTRACT:
There is disclosed the use of decarboxylated rosins as total or partial replacements for oil in rubber formulations. Vulcanizate properties, low temperature performance, and processibility are comparable when using either the decarboxylated rosins or an aromatic extending oil, however, the decarboxylated rosin extended rubber demonstrates improved abrasion resistance.
