    摘要: The present invention concerns a process for producing a synthetic resin foam composed of cells having substantially two sizes, one of the sizes being at most 0.3 mm and the other size as being 0.4 to 1 mm, comprising the steps of:forming a mixture of one or more of a water-absorbent high molecular compound, a cell-controlling agent, a synthetic resin, and water; melting the mixture with heating; incorporating a volatile type foaming agent into the mixture under pressure; and extruding the mixture into a lower pressure space to form a foam.

    摘要: A process for preparing a foamed article of a vinyl chloride resin containing a large amount of inorganic particles, which comprises the steps of preparing a foamable composition of the resin, the inorganic particles and a blowing agent, filling a closable mold with the composition, heating the mold and the composition under pressure, and opening the mold at a temperature of not less than a softening temperature of the resin in the foamable composition. According to the process, a foamed article which has an excellent mechanical property and a high expansion ratio, and produces little calorie, smoke and poison gas can be prepared with reduced energy consumption and in a shortened production time.
