(57) [Abstract] Polystyrene sheet [Problem] Secondary molding with excellent anti-fogging properties at high and low temperatures, excellent releasability and releasability of sheets and sheet secondary molded products, and low charging during molding SOLUTION: As antifogging agent, at least one surfactant selected from sucrose fatty acid esters and polyglycerin fatty acid esters is used in an amount of 5 to 30 mg / surface. m 2 On the opposite side, a mixture of an ether-based polymer and a non-block copolymer type ethylene oxide-based nonionic surfactant as a release agent is 3 to 30 mg / m 2.
