ABSTRACT:
Synthetic diene rubber stock for the production of vulcanized articles can be improved with respect to thermal discoloration at relatively high temperature by mixing therewith a high molecular weight alkylene oxide compound. The high molecular weight alkylene oxide compound also is effective to facilitate the drying operation of the wet rubber stock by means of a screw type drier.
