Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an industrially extremely useful foamable polyolefin bead at a low cost, obtainable as a high-density non-foamed bead advantageous for transportation and preservation, exceeding 450 g/L. SOLUTION: A propylene polymer, a volatile organic blowing agent, a fine particle of a nucleating agent and optionally another conventional additive are melted and compounded in an extruder. The molten mixture is extruded into a water bath at

Abstract: The invention relates to foam beads of propylene polymers which comprise more than 40% of open cells. They are produced by impregnating propylene polymer minigranules which comprise from 1 to 40% by weight of a cell opener with a volatile blowing agent in aqueous suspension and subsequently decompressing the mixture.

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.
