Kind Code:
B2
Abstract:
The object is to establish a production process which can produce a pellet having a low moisture content efficiently and stably even when a highly hygroscopic resin such as an acrylic resin is used. Specifically disclosed is a process for producing an acrylic resin pellet, which comprises the following steps: a molding step of molding an acrylic resin in a molten state into a pellet; and, subsequent to the molding step, a transport step of transporting the pellet into a storage silo (5), wherein the temperature of the pellet is kept at 70°C or higher during the transport step. Also disclosed is an acrylic resin package body comprising an acrylic resin pellet sealed with a material having a water vapor transmission rate of less than 1.0 g/m2/24-hours, wherein the acrylic resin pellet has a moisture content of less than 300 ppm and contains a foreign matter having a diameter of 2 µm or greater in an amount of less than 500 particles/g as measured on a liquid-borne particle counter.
