Production method of thermoplastic resin composition, molded body, and light emission body
View Patent ↗Disclosed is a production method of a thermoplastic resin composition which has a good light emission property of visible light by ultraviolet irradiation, the production method comprising: compounding 0.001 to 50 parts by mass of at least one of metal compound (B) selected from a metal complex (B1) and a metal halide (B2), and 0.001 to 30 parts by mass of a polyalkylene glycol compound (C), with respect to 100 parts by mass of a thermoplastic resin (A); and heating it at a temperature of 100 to 320° C.
1. A method of producing an acrylic resin (A) composition comprising: compounding 0.001 to 50 parts by mass of metal compound (B) comprising a metal halide (B2), and 0.001 to 30 parts by mass of a polyalkylene glycol compound (C), with respect to 100 parts by mass of the acrylic resin (A); and heating them at a temperature of 100 to 320° C.
2. The method of claim 1 , wherein the metal of the metal compound (B) is zinc.
3. The method of claim 1 , wherein the acrylic resin (A) is selected from the group consisting of polymethyl methacrylates, acrylic resins obtained by copolymerization of methyl methacrylate with one or more additional monomers, polymers containing acrylates or methacrylates as a main component, acrylic resins obtained by graft copolymerization of a polymer containing a rubber, with at least one additional monomer, and mixtures thereof.
4. The method of claim 1 , wherein the acrylic resin (A) has a mass average molecular weight of 1,000 to 1,000,000.
5. The method of claim 1 , wherein the acrylic resin (A) has a mass average molecular weight of 5,000 to 800,000.
6. The method of claim 1 , wherein the acrylic resin (A) has a mass average molecular weight of 10,000 to 500,000.
7. The method of claim 1 , wherein the metal compound (B) comprises the metal complex (B1).
8. The method of claim 1 , wherein the polyalkylene glycol compound (C) is selected from the group consisting of polyalkylene glycols, polyalkylene glycol monoalkyl ethers, polyalkylene glycol dialkyl ethers and mixtures thereof.
9. The method of claim 1 , further comprising molding the acrylic resin composition to obtain a molded body.
10. The method of claim 2 , further comprising molding the acrylic resin composition to obtain a molded body.
11. The method of claim 9 , further comprising incorporating the molded body into a light emission body.
