    摘要： In a process for producing a plate-like polystyrene resin foam which comprises extruding a molten mixture consisting of a polystyrene resin and a volatile blowing agent by an extruder into a zone having a lower pressure than the inside of the extruder; the improvement wherein said volatile blowing agent is a mixture consisting of dichlorodifluoromethane, ethyl chloride and methyl chloride in which dichlorodifluoromethane accounts for 50 to 70% by weight of the mixture and the remainder consists of ethyl chloride and methyl chloride and the amount of ethyl chloride is at least 30% by weight based on the total amount of ethyl chloride and methyl chloride; and wherein said volatile blowing agent is present in said molten mixture in a proportion of 8 to 17 parts by weight per 100 parts by weight of the polystyrene resin component.

    摘要： A light diffusing laminated plate including a first light diffusing layer containing particles of a transparent light diffusing material dispersed therein and having a concave cross-section, and a second light diffusing layer containing particles of an opaque light diffusing material dispersed therein and having a convex cross-section. The first and second light diffusing layers are laminated together such that the convex and concave surfaces are face to face contact with each other to form a curved interface therebetween. The first and second light diffusing layers have a substantially uniform cross-section in one direction. A transmissive screen for a rear projection display device having a light image source, including the above light diffusing laminated plate and a lens system disposed such that a light image from the source is projected through the light diffusing laminated plate and the lens system and displayed on the screen.

    摘要： A gas-barrier multilayered structure comprising (A) at least one layer of a copolyamide composed of (a) a dicarboxylic acid component composed of 55 to 70 mole % of an aliphatic dicarboxylic acid component and 45 to 30 mole % of an aromatic dicarboxylic acid component consisting substantially of 20 to 30 mole % of isophthalic acid and 5 to 20 mole % of terephthalic acid, and (b) a diamine component composed substantially of a m-xylylenediamine component, and (B) at least one layer of a thermoplastic resin other than the copolyamide. Instead of the layer (A), there can be used (A') at least one layer of a mixture of 40 to 60 % by weight of a first copolyamide composed of (a) a dicarboxylic acid component composed of 55 to 70 mole % of an aliphatic dicarboxylic acid component and 45 to 30 mole % of an aromatic dicarboxylic acid component consisting substantially of 20 to 30 mole % of isophthalic acid and 5 to 20 mole % of terephthalic acid and (b) a diamine component composed substantially of m-xylylenediamine and 60 to 40 % by weight of a second polyamide composed of a dicarboxylic acid component consisting substantially of an aliphthalic dicarboxylic acid component and a diamine component consisting substantially of a m-xylylenediamine component.
