[0284] (i-1) 70 parts by mass and (ii) 0.7 parts by mass were mixed with a drum mixer, and the powder mixture was extruded from a TEM58SS twin-screw extruder (manufactured by Toshiba Machinery Co., Ltd., number of barrels 13, screw diameter 58 mm, L / D=53; screw mode with kneading disc L: 2, kneading disc R: 14 and kneading disc N: 2) the most upstream part (top feed port) supply, at the barrel temperature Melt kneading was carried out under the conditions of 300° C., screw rotation speed of 400 rpm, extrusion speed of 400 kg / hr, and exhaust port vacuum of 7.998 kPa (60 Torr) to obtain pellets. The pellets were dissolved in chloroform, followed by reprecipitation with methanol to extract polyphenylene ether components. Thereafter, it was vacuum-dried at 60° C. for 4 hours to obtain a polyphenylene ether powder.

[0285] The resulting polyphenylene ether powder can be used 31 P-NMR (single plus method) and 1 H-NMR was identified, and the addition amount of the reactive compou...

[0332] A mixture of (i-2) 70 parts by mass and (ii) 0.7 parts by mass was melt-kneaded in the same manner as in Example 1 to obtain pellets. The obtained pellets were made into polyphenylene ether powder, and the addition amount of the reactive compound was quantified in the same manner as in Example 1. As a result, it was confirmed that the chemical formula (9) per 100 monomers in the polyphenylene ether chain , and (10) have a total of 0.26 structural units.

[0333] Furthermore, the amount of addition on the terminal hydroxyl group can be utilized 13 C-NMR, using the peak integral value [A] of 146.4ppm (the carbon adjacent to the oxygen atom of the ether bond (which is formed by adding a reactive compound to the OH group), 145.4ppm (the carbon adjacent to the OH group) The integral value [B] of the adjacent carbon) was obtained from the above formula (1), and it was confirmed that 0.04 structural units of the chemical formula (11) were included in every 100 monomer units c...

[0337] A mixture of (i-1) 40 parts by mass, (i-2) 30 parts by mass, and (ii) 0.7 parts by mass was melt-kneaded in the same manner as in Example 1 to obtain pellets. The obtained pellets were made into polyphenylene ether powder, and the addition amount of the reactive compound was quantified in the same manner as in Example 1. As a result, it was confirmed that the chemical formula (9) per 100 monomers in the polyphenylene ether chain , and (10) have a total of 0.28 structural units.

[0338] Furthermore, the amount of addition on the terminal hydroxyl group can be utilized 13 C-NMR, using the peak integral value [A] of 146.4ppm (the carbon adjacent to the oxygen atom of the ether bond (which is formed by adding a reactive compound to the OH group), 145.4ppm (the carbon adjacent to the OH group) The integral value [B] of the adjacent carbon) was obtained from the above formula (1), and it was confirmed that 0.03 structural units of the chemical formula (11) were included in ...

Abstract

The invention provides a laminated molded article having high surface reflectance and excellent close adhesion between a molded product formed from a resin composition and a metal thin-film layer. Thelaminated molded article includes a molded product formed from a resin composition and a metal thin-film layer. The resin composition contains a polyphenylene ether resin (A) and an amorphous [alpha]-olefin copolymer (B). The polyphenylene ether resin (A) includes a polyphenylene ether (i) and a compound (ii) being at least one compound selected from the group consisting of: an organophosphorus compound having, in molecules thereof, a chemical structure represented by formula (I) or (II), where R in formula (II) is a trivalent saturated hydrocarbon group having a carbon number of 1 to 8 or atrivalent aromatic hydrocarbon group having a carbon number of 6 to 12; and a phosphonic acid, phosphonic acid ester, phosphinic acid, phosphinic acid ester, monocarboxylic acid, sulfonic acid, sulfinic acid, or carbonate other than the organophosphorus compound in amounts of 95 mass % to 99.95 mass % of the component (i) and 0.05 mass % to 5 mass % of the component (ii) relative to 100 mass %, intotal, of the components (i) and (ii).

Description

【Technical field】 [0001] The present invention relates to a laminated molded article comprising a molded article made of a polyphenylene ether resin composition and a metal thin film layer. 【Background technique】 [0002] Polyphenylene ether resin has many characteristics such as mechanical properties, electrical properties, acid and alkali resistance, heat resistance, low specific gravity, low water absorption, and good dimensional stability, so it is used as a home appliance, OA equipment, and office equipment. , information equipment and automobiles are widely used. In recent years, studies on polyphenylene ether-based resin compositions have also been carried out for use in optical system components for automobiles, projectors, various lighting fixtures, and the like. [0003] A laminated molded article including a molded article made of a resin composition and a metal thin film layer is used in applications such as automotive optical components, projectors, and various...
