Abstract: Manufacture of expandable styrene polymers which on expansion provide oval saddle-shaped discs suitable for use as bulk cushioning material. In the process, cylindrical extrudates of expandable styrene polymers are deformed at form 70* to 90*C by means of rollers to form strands of oval cross-section, which strands are then sliced to form discs by cutting in the direction of the short axis of said oval cross-section.

Abstract: The invention relates to pre-expanded plastic beads based on poly-para-methylstyrene with the following properties: (a) the bead size lies between 0.2 and 3 cm, (b) the thermal stability, measured in accordance with DIN 53,424 is above 110.degree.C, and (c) the bulk density is below 35 g/l. The corresponding expandable plastic beads are prepared through the polymerization of para-methylstyrene in an aqueous suspension with the addition of volatile organic blowing agents during or after polymerization, whereby polymerization occurs in the presence of molecular-weight-regulating substances. Typical molecular-weight-regulating substances are organic chain transfer agents with a transfer constant K between 0.1 and 50, said agents being added in amounts ranging from 0.1 percent by weight to 1 percent by weight when a yield ranging from 20 to 95 percent is reached. Oligomers of the styrene or para-methylstyrene in quantities from 0.1 percent by weight to 10 percent by weight may also be employed.

Abstract: Particulate expandable styrene polymers containing organic bromine compounds and, to improve processability, from 0.0001 to 1.0% by weight, based on the styrene polymer, of an amine which is soluble in styrene and free from hydroxyl groups. The organic bromine compounds are present in an amount of 0.05 to 3% by weight. The amine compound has the general formula NR1R2R3 in which R1 is an aliphatic or cycloaliphatic hydrocarbon radical of from 4 to 20 carbon atoms, R2 is hydrogen or an aliphatic or cycloaliphatic hydrocarbon radical of from 1 to 15 carbon atoms and R3 is hydrogen or an aliphatic or aromatic hydrocarbon of from 1 to 15 carbon atoms, with the proviso that R1 has from 6 to 20 carbon atoms when R2 and R3 are both hydrogen.

Abstract: The present invention relates to novel coating agents based on mono- and/or poly- urethanes melting below 150.degree.C for expandable particulate styrene polymers. These agents have no detrimental effect on the styrene polymers, lead to very fast-cooling moldings showing uniform density distribution throughout and good fusion, and give higher space/time yields during prefoaming.
