Title:
METHACRYLATE RESIN COMPOSITION, METHOD FOR PRODUCING SAME, MOLDED BODY, FILM, LAMINATED FILM, AND LAMINATED MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2018/021449
Kind Code:
A1
Abstract:
The present invention provides a methacrylate resin composition from which a molded body having excellent high-temperature formability and high dimensional stability against heat can be obtained. This methacrylate resin composition is made of a methacrylate resin (M1) having an α relaxation temperature Tα1 of at least 137oC at the time of dynamic viscoelastic measurement in a tensile mode at 1 Hz, and a methacrylate resin (M2) having an α relaxation temperature Tα2 of 132oC or lower at the time of dynamic viscoelastic measurement in a tensile mode at 1 Hz. When the melt viscosities of the methacrylate resin (M1) and the methacrylate resin (M2) at a temperature of 260oC and a shear rate of 122 sec-1 are η1 and η2, respectively, η1 is greater than η2, and the mass ratio of the methacrylate resin (M1)/the methacrylate (M2) ranges from 2/98 to 30/70.
