| titleOfInvention | Novel unsaturated polyester resin composition, molding material, reinforced plastic molded article, which is made of modified PET and PEN which are recycled materials and has improved water resistance, and a method for short-time synthesis of this composition |
| abstract | An object of the present invention is to decompose and resynthesize a recycled material such as PET or PEN without using a special material during the synthesis of an unsaturated polyester resin, or at the reaction end point (acid value, viscosity, molecular weight). ), It is possible to obtain a molded article with improved hot water resistance without changing the compounding amount of the polymerizable monomer, and to synthesize the unsaturated polyester resin in a short time. Provided is a production method capable of synthesizing a composition in a short time using a special synthesis apparatus. According to the present invention, a chemical reaction is carried out by a stirring and mixing operation, and a reverse reaction is suppressed by discharging a reaction by-product to the outside of the system. The use of a reactor capable of shortening the processing time per batch as compared with the conventional apparatus while supplying or removing the required amount of heat as compared with the conventional batch type stirring apparatus of the present invention makes the present invention inconvenient. The saturated polyester resin composition can be synthesized in a short time with improved hot water resistance, and can provide a resin composition that can be used for molded articles around water.
