摘要： A process for producing a solvent-free acrylic sheet includes a coating step which may involve either coating at least one support with a solvent-free syrupy composition for coating polymerization or applying the solvent-free coating polymerization syrupy composition between at least two supports at a coating thickness of at least 0.15 mm to form a laminate. The solvent-free coating polymerization syrupy composition includes an acrylic vinyl monomer capable of radical polymerization.The process further includes a heating polymerization step in which the laminate is heated at 60.degree. C. or higher for reaction initiation so that autoexotherm is induced to cause the acrylic vinyl monomer to polymerize.The process concludes with an aging polymerization step in which the laminate having undergone the heating polymerization step is maintained at a temperature that is at least 30.degree. C. but lower than the heating temperature of the heating polymerization step so that a polymerization reaction is effected until the content of residual monomer in the laminate is 2% by weight or less based on the solvent-free coating polymerization syrupy composition to produce a thick acrylic sheet.
