Abstract

Disclosed is an olefinic, polymeric composition and a method for making such polymeric composition wherein the composition includes 10%-90% modified sulfur. The sulfur is modified by the addition of at least one plasticizer and a thiophilic, nitrogen-containing compound as a viscosity regulator. In accordance with the invention, elemental sulfur is modified by the addition of any of several plasticizers in amounts of about 1%-20% by weight based on sulfur and the addition of up to about 5% by weight of a thiophilic, nitrogen-containing compound such as any of various amines or amides.
