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.

Polymeric compositions of olefinic polymers obtained by radical polymerization or additive reaction, characterized in that they contain 10 to 90 percent by weight of sulfur modified by means of at least one plasticizer and a thiophilic, nitrogen-containing compound as a viscosity regulator.
Polymeric compositions in the form of dispersions, of olefinic polymers obtained by radical polymerization or additive reaction in 10 to 90 percent by weight of sulfur which has been modified by means of plasticizers containing at least one thiophilic, nitrogen-containing viscosity regulator.
A process for the production of a polymeric composition comprising the steps of:
- treating sulfur with at least one plasticizer and at least one thiophilic, nitrogen-containing viscosity regulator to produce a modified sulfur and dispersing an olefinic polymer in the modified sulfur.
