Attempts to use conventional linear dibasic acid esters (such as dioctyl adipate, dioctyl sebacate and di-2-ethylhexyl sebacate) or phthalate esters (such as di-2-ethylhexyl phthalate) have also been unsuccessful, since such conventional ester plasticizers are either incompatible with the elastomer, resulting in exudation of the plasticizer, or are too volatile for many elastomer uses.
