    Abstract: PROBLEM TO BE SOLVED: To obtain an expandable styrene polymer containing a foaming agent and a specific foaming auxiliary and exhibiting an improved expandable characteristic without affecting other treating characteristics and product characteristics. SOLUTION: This expandable styrene polymer contains a foaming agent and 0.5-20wt.% of a foaming auxiliary. Therein, the foaming auxiliary comprises a 2-20C aliphatic olefin oligomer which is liquid at room temperature and has a number - average polymerization degree of 2-200, preferably 2-100, and plural terminal double bonds, such as propene oligomer or isobutene oligomer.

    Abstract: The invention relates to a method for producing expanded or expandable polyolefin particles, by impregnating polyolefin granulate with a volatile propellant in suspension under pressure. A mixture of a water-insoluble inorganic compound and a surfactant is used as a suspending auxiliary agent and the impregnation takes place in the presence of a surface-active polymer which carries carboxyl or carboxylate groups.

    Abstract: The invention relates to a process for the production of expanded or expandable polyolefin beads by impregnating polyolefin granules with a volatile blowing agent in suspension under pressure. As suspension aid, use is made of a mixture of a water-insoluble inorganic compound and a surfactant, and the impregnation is carried out in the presence of a surface-active polymer carrying carboxyl or carboxylate groups.
