More Information
Summary:The present invention provides a (methyl)acrylic syrup which can give a molding material excellent in storage stability and provide a process for producing this (methyl)acrylic syrup within shorter time as compared to the conventional. Furthermore, the present invention provides a molding material which can be cured more quickly, and excellent in resistances to heat, solvents, weather, and water. This (methyl)acrylic syrup is produced, for example, by polymerizing (methyl)acrylic ester monomers with carboxylic vinyl in the presence of thiol compounds and then treating the reaction mixture with maleic anhydride and basic compounds. This molding material contains the (meth)acrylic syrup and it can optionally contains a thickener, a succinic acid derivative, a reinforcement, etc.
