EASILY SURFACE-SHAPABLE SHEET, EASILY SURFACE-SHAPABLE SHEET LAMINATE, AND SURFACE-SHAPING METHOD AND FORMED ARTICLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an easily surface-shapable sheet that permits easy shaping of its surface into a wide variety of forms having ultrahigh precision, a high aspect ratio or the like and is excellently handleable, an easily surface-shapable sheet laminate, a surface-shaping method and a formed article using the same.;SOLUTION: The easily surface-shapable sheet comprises, as a main component, a polyester resin comprised of at least a recurring unit bearing a fluorene skeleton as a copolymerization component and satisfies the following requirements (A)-(C): (A) A crystallization enthalpy ΔHcc in a temperature-raising process (temperature raising rate: 2°C/min) obtained by the differential scanning calorimetry (DSC) is at most 1 J/g. (B) A dynamic storage modulus E1' at 25°C obtained by the dynamic viscoelastic measurement (DMA) is 0.1×10⁹ to 2.5×10⁹ Pa. (C) A dynamic storage modulus E2' obtained by DMA at a temperature of its glass transition temperature (Tg)+30°C is 1×10⁴ to 5×10⁶ Pa.;COPYRIGHT: (C)2007,JPO&INPIT
