Abstract
Polyolefin foam materials of high dimensional stability at elevated temperatures are produced from modified polypropylenes and unmodified polypropylenes. The modified polypropylenes used are produced by mixing polypropylene particles with thermally decomposing free radical-forming agents, absorbing readily volatile bifunctional monomers and heating and melting the mixture. Areas of application for the polyolefin foam materials of high dimensional stability at elevated temperatures are the packaging sector, motor vehicle parts, sports and leisure equipment, industrial applications, as well as applications in the building sector.
