Summary: | The present invention provides (meth)acryl syrup which shows excellent storage stability as a molding material, and also provides a method of manufacturing the (meth)acryl syrup in a shorter period of time compared with the conventional method, and a molding material which permits a molded article having excellent heat-resistance, solvent-resistance, weathering resistance, and water-resistance, etc., to be manufactured. The (meth)acryl syrup is manufactured, for example, by polymerizing a monomer component including (meth)acrylic ester and a vinyl monomer having a carboxyl group in a presence of a thiol compound, and subsequently processing the reaction mixture with maleic anhydride and a basic compound. The molding material includes the (meth)acryl syrup, and may also include a thickening agent, derivatives of succinic acid, a reinforcing material, etc. |
