Abstract:
A process for producing an additive-containing resin molded article, which comprises melt-molding a thermoplastic polyester resin, wherein a multi-functional additive having two or more of the same or different functional groups each selected from the group consisting of a hydroxyl group, carboxyl group, amino group, or ester bond is added to said resin and each of the said functional groups of said additive and is allowed to react with polymer molecules of the polyester resin which is in a molten state, wherein said additive is an ultraviolet absorber selected from 2,2â€²-methylenebis-[4-(hydroxyethyl)-6-(2H-benzotriazol-2-yl)phenol], 2,2â€²-methylenebis-[3-(carboxyl)-6-(2H-benzotriazol-2-yl)phenol], 2,2â€²-methylene-[(4-hydroxyethyl-4â€²-carboxyl)-6,6â€²-(2H-benzotriazol-2-yl)phenol], and 2,2â€²-methylenebis-[4-(hydroxyoctyl)-6-(2H-benzotriazol-2-yl)phenol], a flame retardant comprising any one of dibutylbishydroxypropyl pyrophosphate, dibutyltrishydroxypropyl triphosphate, and phenyl-bis(2-methacryloyloxyethyl) phosphate, a stainproofing agent comprising any one of &agr;,&ohgr;-diaminopolydimethylsiloxane and fluorinated bisphenol A, an antioxidant comprising bis-(4-hydroxethylphenyl)amine, or an antistatic agent comprising any one of stearoamidopropyldimethyl-&bgr;-hydroxyethylammonium dihydrogen phosphate and N,N-bis(2-hydroxyethyl)-N-(3-dodecyloxy-2-hydroxypropyl) methylammonium methosulfate.
