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.

[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 phenol / 1,1,2,2-tetrachloroethane mixed solution (weight ratio (3 / 2)).

[0133] (3) Melt viscosity: It measured using the Toyo Seiki Co., Ltd. Cayapirograph (IC type). 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 within 3 minutes...

[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, mix at room temperature for 1 hour, then raise the temperature to 150° C. over 5 hours, at which point 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 Base (DOP-X).

[0143] To the obtained DOP-X was added 500 parts of toluene, stirred at room temperature for about 1 hour, and the supernatant was removed to purify DOP-X.

[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, in the molten state, it...

Abstract

The present invention provides a thermoplastic resin composition for a master batch, which is characterized in that it contains an organophosphorus compound represented by the general formula (1) and a thermoplastic resin, the phosphorus content is 5000 ppm or more, and the general formula (1) (wherein, R1 and R2 represent an organic group or a halogen atom, and m and n represent an integer of 0 to 4. When m or n is an integer of 2 to 4, each of R1 and R2 may be the same or different). The thermoplastic resin composition for a master batch can be mixed with a thermoplastic resin of the same kind or a different kind even when the phosphorus content is increased to impart flame retardancy to obtain a thermoplastic resin composition that can be easily molded.

Description

technical field [0001] 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 obtained thermoplastic resin composition can be used in fibers for clothing, fibers for industrial goods, films, engineering plastics, or adhesives by extrusion molding, injection molding, or the like. Background technique [0002] Generally, when imparting flame retardancy to a thermoplastic resin, a method of adding a flame retardant (compound, monomer, etc.) to a common thermoplastic resin can be employed. However, due to t...
