Abstract: The invention relates to expandable olefin bead polymers which comprise a blowing agent with a boiling point of from -5 to 150° C., selected from the group consisting of alkanes, alkanols, ketones, ethers and esters. The particles are unfoamed and have a bulk density above 500 g/l, and can be foamed to a bulk density below 200 g/l after storage for one hour at room temperature in free contact with the atmosphere. They are prepared by impregnating polyolefin pellets in suspension in a pressure vessel with the blowing agent, cooling the batch below 100° C., reducing the pressure and isolating the particles.

Abstract: The invention relates to the essentially salt-free coagulation of plastic or rubber dispersions using shearing forces. A device with at least one shearin g element (3) is used to this end. Said device has a stator (7) and a rotor (9 ) which is arranged inside said stator, the surfaces of the stator and the rot or that point towards each other each being flat. Alternatively, at least the rotor has a structure which is configured on its surface and which points in the direction of the stator from said surface. A gap (11) with a predetermin ed gap width is configured between the stator and the rotor. The method is carried out in such a way that the dispersion to be coagulated is guided through the gap (11) between the stator (7) and the rotor (9) and precipitat ed through the rotation of the rotor at a predetermined shear speed and with a predetermined shear deformation.

Abstract: The adhesive is held in an air- and watertight casing (5) in the groove (3). During adhesion, the tongue (9) is inserted in the groove, breaking the casing and releasing adhesive. Preferred features: The casing is an extruded flexible tube inserted into the groove, being filled in a second stage. It is alternatively filled during manufacture. The method is applicable in a general sense, to projection and recess jointing of objects.

Abstract: The invention relates to a method for producing expandable polystyrene with a molecular weight Mw in excess of 170,000 g/mol. According to the invention, a styrene polymer melt containing an expanding agent and having a temperature of at least 120 ~C is passed through a spinneret comprising bores, whose diameter at the spinneret exit measures a maximum 1.5 mm, and is then granulated. The invention also relates to expandable styrene polymers (EPS) with a molecular weight Mw of more than 170,000 g/mol and between 0.05 and 1.5 wt. % inherent moisture.
