Abstract
Official abstract text for this publication.
Disclosed is a production method of a thermoplastic resin composition comprising: compounding 0.001 to 50 parts by mass of a metal complex (B) with respect to 100 parts by mass of a thermoplastic resin (A), and kneading it under a condition of a kneading temperature of 225 to 300° C. and of a kneading time of 0.5 to 20 minutes, wherein a metal of the metal complex (B) is a metal except for zinc; a molded body obtained by molding the thermoplastic resin composition which is obtained by the production method; and a light emission body using the molded body.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for production of a thermoplastic resin composition, the method comprising: compounding a thermoplastic acrylic resin (A) and from 2.5 to 5 parts by mass of a metal complex (B) with respect to 100 parts by mass of the thermoplastic acrylic resin (A), thereby forming a mixture, and kneading the mixture at a temperature of from 225 to 300° C. for form 0.5 to 30 minutes, wherein a metal of the metal complex (B) is aluminum and zinc is excluded, wherein the thermoplastic acrylic resin (A) is polymethyl methacrylate (PMMA), and wherein the metal complex (B) is at least one complex selected from the group consisting of aluminum acetylacetonate and aluminum hexafluoroacetylacetonate. 2. The method according to claim 1 , wherein the thermoplastic resin composition further comprises at least one additive selected from the group consisting of a plasticizer, a lubricant, a stabilizer, an oxidant inhibitor, an ultraviolet absorber, and a mold release agent. 3. The method according to claim 1 , wherein the mixture is kneaded at the temperature of from 240 to 290° C. 4. The method according to claim 1 , wherein the metal complex (B) is aluminum hexafluoroacetylacetonate. 5. The method according to claim 1 , wherein the metal complex (B) is aluminum acetylacetonate.
