Solution Polymerized Butadiene/Styrene Rubbers for Wire and Cable Applications

摘要

A new family of solution butadiene/styrene copolymers was shown to possess unique attributes not attainable with SBR. Blends of block and random copolymers yield excellent processing and extrusion characteristics, superior low temperature properties, much better aging resistance, and better electrical properties than SBR. The work reported was restricted to commercially available rubbers. Numerous other types of copolymers can be prepared by the solution technique which possess other interesting attributes. By knowing the end-product requirements and relating these to basic properties of the rubbers, it is possible to design polymers to meet almost any requirement. (Author)
