Abstract
This invention relates to improved blend compositions of a neutralized sulfonated elastomeric polymer and a non-polar backbone process oil which is either paraffinic or naphthenic and has less than 0.75 wt. % of polar type compounds and less than 20 wt. % of aromatic type. These oil extended sulfonated elastomeric products have improved compression set properties as compared to previously existing products.
