    • Provided is a method of producing a resin molded article which hardly involves the occurrence of optical distortion and of sink marks. The method of producing a resin molded article includes: a first step including pouring a polyfunctional (meth)acrylic monomer into a molding die and irradiating the polyfunctional (meth)acrylic monomer with radiant energy rays until a polymerization conversion degree reaches 1 to 10% to polymerize a part of the polyfunctional (meth)acrylic monomer; and a second step including heating the polymerized polyfunctional (meth)acrylic monomer after the first step in a state where the polymerized polyfunctional (meth)acrylic monomer is held in the molding die to further polymerize a remaining part of the polyfunctional (meth)acrylic monomer until the polymerization conversion degree reaches 60% or more.
    • 本发明提供一种难以发生光学变形和凹痕的树脂成形体的制造方法。 制造树脂成型体的方法包括:第一步骤,将多官能(甲基)丙烯酸单体倒入成型模具中,并用辐射能射线照射多官能(甲基)丙烯酸类单体,直至聚合转化率达到1〜10%〜 聚合一部分多官能(甲基)丙烯酸单体; 以及第二步骤,其中在聚合的多官能(甲基)丙烯酸单体保持在成形模具中的状态下,在第一步骤之后加热聚合的多官能(甲基)丙烯酸单体,以进一步聚合剩余部分的多官能(甲基)丙烯酸单体 直到聚合转化度达到60%以上。
