Abstract: of the disclosure: Particulate polystyrene containing blowing agent and having improved expandability is based on polystyrene having a weight-average mean molecular weight of not more than from 130,000 to 180,000 and a molecular weight distribution curve in which the high molecular weight flank drops steeply. The expandable polystyrene particles are produced by polymerizing styrene in aqueous suspension in the presence of blowing agents and of chain transfer agents or styrene oligomers.

Abstract: Particulate expandable styrene polymers which contain from 0.0001 to 0.2% by weight, based on the styrene polymer, of an inhomogeneously distributed nucleating agent for expandable polystyrene, the nucleating agent being present only in a peripheral zone of the particles whilst the interior of the particles is free from nucleating agent. Nucleating agents which may be used are organic compounds having at least three bromine atoms, bonded to aliphatic or cycloaliphatic structures, in the molecule, or bromine compounds which are polymerizable, or are copolymerizable with styrene.
