摘要： Conventional moldings of foamed particles of propylene polymers have been estimated to be excellent in cushioning effect and impact resilience but not necessarily satisfactory in stiffnesses such as compressional stress. The formed particles of propylene homopolymers of the invention have a modulus in tension of 15,000-25,000 kg/cm2 and a crystal structure which exhibits both of proper and high-temperature peaks as the endothermic peak in the DSC curve obtained by differential scanning calorimetry, the high-temperature peak having a heat quantity of 30-60 J/g. Moldings produced from the above foamed particles have a density of 0.01-0.3 g/cm3 and a modulus in tension of 15,000-25,000 kg/cm2. The DSC curves thereof reveal that, as in the case of the foamed particles per se, the crystal structures exhibit both of the proper and high-temperature peaks and the high-temperature peak has a heat quantity of 30-60 J/g, as well.
