Abstract: 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.

Abstract: An extruded synthetic resin foam comprises a cell structure of substantially two different cell sizes, the smaller size being not more than about 0.25 mm while the other size is from about 0.4 to about 1 mm. The cells are dispersed in an island in the sea manner. A foam such as a styrenic foam is produced by forming a mixture of synthetic resin, a fine mineral powder having hydroxyl groups, and a cell controlling agent, incorporating a volatile foaming agent and extruding the mixture to form a foam. The powder has a particle size of not more than 1000 nm and may be a silica having silanol groups.

Abstract: A benzothiazole of the following formula ##STR1## in which R represents a methyl, methoxy, carboxyl or methoxycarbonyl group. The compound is useful for treating rheumatic arthritis.

Abstract: 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.
