Fine particulate, expandable styrene polymers suitable for the production of rapidly mold-ejected cellular bodies

摘要

Fine particulate expandable styrene polymers suitable for the production of molded bodies with improved minimum mold dwell times, containing 0.01 to 2.0% by weight, referred to the polystyrene or the total of the polymerized monomers, of polyoctenamer having I values from about 10 to 400 ml/g and trans octylene contents from about 20 to 90%.
