Problems solved by technology

However, when the proportion of CPPA added to the thermoplastic resin increases, although the copolymerization can be carried out, the melt viscosity of the obtained thermoplastic resin fluctuates greatly, and it is difficult to adjust the melt viscosity, so it is also difficult to adjust the chip shape.

Embodiment

[0129] The present invention will be specifically described below using examples, but the present invention is not limited to the examples shown below. Wherein, "parts" and "%" in each example are based on weight. In addition, each evaluation value is the value measured by the following method.

[0130] (Physical properties of thermoplastic resin composition for masterbatch, etc.)

[0131] (1) Element content: Metal zinc content and phosphorus content were measured by atomic absorption analysis.

[0132] (2) Intrinsic viscosity: Measured at 30°C with a mixed solution of phenol / 1,1,2,2-tetrachloroethane (weight ratio (3 / 2)).

[0133] (3) Melt viscosity: Measured using a Capirograph (IC type) manufactured by Toyo Seiki Co., Ltd. The inner diameter of the cylinder is 10mm. Fill the cylinder with the sample while sparging with nitrogen. Complete sample filling within 30 seconds. After filling the sample, start the measurement 3 minutes later, and finish the measurement withi...

[0141] (Synthesis of organophosphorus compounds)

[0142] 4.9 parts of toluene was added to 1000 parts of crude ortho-phenylphenol (OPP) with a purity of 95%, stirred at room temperature for about 1 hour, and the supernatant was removed. Next, add 1,000 parts of o-phenylphenol and 1,009 parts of phosphorus trichloride to the reactor at a molar ratio of 1:1.25. After mixing at room temperature for 1 hour, the temperature is raised to 150° C. in 5 hours. At this time, hydrogen chloride. Add 5.9 parts of zinc chloride to it, and react at 200°C for 4 hours to obtain 6-chloro-(6H)-dibenzo-(c,e)(1,2)-oxadiethoxyphosphorylthiochol Alkali (DOP-X).

[0143] Add 500 parts of toluene to the obtained DOP-X, stir at room temperature for about 1 hour, remove the supernatant, and perform purification of DOP-X.

[0144] Furthermore, 77 parts of water was added thereto to make the molar ratio of water to o-phenylphenol 1:1, and 1000 parts of toluene was added to carry out hydrolysis under r...

[0149] (Preparation of thermoplastic resin composition (II) for masterbatch)

[0150] In a stainless steel autoclave equipped with a stirrer, a distillation tower, and a pressure regulator, put 832 parts of terephthalic acid and 1,000 parts of the organophosphorus compound (GHM) obtained in the above Reference Example 1 (50% ethylene glycol solution / With respect to the obtained polymer, the phosphorus content is 30000ppm) and 184 parts of ethylene glycol, and then add 0.62 parts of antimony trioxide and 3.26 parts of triethylamine, at 245 ° C, 2.5 kg / cm 2 Under gauge pressure, the esterification reaction was carried out for 2 hours while removing water generated by the esterification one by one. Next, the temperature of the system was raised to 275° C. over 1 hour, while the pressure of the system was gradually reduced to 0.1 mmHg, and polycondensation was carried out under these conditions until the melt viscosity reached 3500 poise (275° C.). Then, it is sprayed from a ci...

Abstract

A thermoplastic resin composition for masterbatches which comprises an organophosphorus compound represented by the general formula (1): (1) (wherein R<1> and R<2> each represents an organic group or halogeno; and m and n each is an integer of 0 to 4, provided that when m or n is an integer of 2 to 4, then R<1>'s may be the same or different or R<2>'s may be the same or different) and a thermoplastic resin and which has a phosphorus content of 5,000 ppm or higher. Even when the thermoplastic resin composition for masterbatches has a heightened phosphorus content so as to have flame retardancy, it can be mixed with thermoplastic resins of the same or a different kind to give easily moldable thermoplastic resin compositions.

Description

[0001] This application is the application number 200480036733.5 (PCT / JP2004 / 018266) filed by the applicant on December 8, 2004, and the title of the invention is "The thermoplastic resin composition for masterbatch and its molding material manufacturing method, and the thermoplastic resin composition using these A divisional application of the international application of "resin composition and its manufacturing method". technical field [0002] This invention relates to the thermoplastic resin composition for masterbatches whose phosphorus content is 5000 ppm or more. In addition, it also relates to a method of producing a chip-shaped molding material from the thermoplastic resin composition for masterbatch. The thermoplastic resin composition for masterbatch of the present invention can be easily mixed with the same or different thermoplastic resin (base resin) as a masterbatch, and various thermoplastic resin compositions having flame retardancy can be obtained. The obtai...
