Abstract
This invention specifically discloses a process for heating trans-1,4-polybutadiene to a temperature at which it can be processed without causing oxidative gelation which comprises heating the trans-1,4-polybutadiene by exposing it to electromagnetic radiation having a frequency in the range of about 2 MHz to about 80 MHz, wherein the trans-1,4-polybutadiene is oil-extended with at least 10 phr of a processing oil.
