Description

Additive for polymer and preparation method thereof, and polymer composition composed thereof Technical field

The present invention relates to an additive, and more particularly to an additive for a thermoplastic polymer, a process for the preparation thereof, and a polymer composition composed of the same.

Background technique

Tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyloxymethyl)methane as described above is an important commercial additive for thermoplastic polymers. For example, it protects organic materials, especially thermoplastic polymers, from degradation by heat, oxidation and/or actinic. Generally, the addition reaction of 2,6-di-tert-butylphenol and methyl acrylate is carried out to form methyl β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, and then It is obtained by transesterification with pentaerythritol. The tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl)methane described in the above formula is used as an additive in a polymer such as polypropylene or polystyrene.

As the public's awareness of environmental protection and health has increased, people have placed higher demands on indoor odor and air quality. Polymers are used as materials for home appliances, OA, packaging materials, daily necessities, toys, sports equipment, shoe materials, cables, instrumentation, electronic components and equipment, building materials and automotive materials, especially home appliances, OA. , toys and automotive materials, stricter odor and VOC requirements.

In the synthesis, preparation, modification and molding process, an auxiliary agent, especially the tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl)methane, is added. The melt stability of the polymer is challenged, and the polymer emits a part of the volatiles, which are generally derived from residual monomers, solvents, additives, and small molecules produced by degradation.

At present, the method of adding a stripping agent, that is, assisting devolatilization, can significantly reduce the odor, residual monomer, solvent and VOC content of the polymer. For example, R.J. Orbrecke "Polymerization" refers to a method in which a single-screw extruder and a twin-screw extruder are simultaneously introduced into a stripping agent to carry out devolatilization. Further, as described in U.S. Patent Nos. 5,380,822 and 5,315,813, a method of removing residual monomers from a polymer comprises pouring water into a melt or a suitable condensable fluid, and then passing the effluent through a flash tank. Chinese Patent No. 98124504.8 discloses a method for removing volatile materials, comprising discharging a foaming aid with a nozzle device, adding it in the opposite direction to the composition stream, and applying the composition under pressure without foaming. Introduced into the mixing device for mixing, and then extruded into the devolatilization tank by an extrusion device to make the polymer at a pressure and temperature of 1.4 or higher. As a foaming product, thereby removing volatile materials, although the above method can obtain a polymer composition having a low amount of volatile materials, since a stripping agent is directly added to a raw material, a large amount of a stripping agent cannot be immersed in the raw material. On the one hand, it is difficult to operate the screw extruder. On the other hand, even if it is added to the screw extruder, the stripping agent is easily vaporized and overflows at the feeding port due to the high temperature of the extruder. The effect is therefore required to use a special injection nozzle with adjustable flow and ejection function, and a pressurized mixing zone is needed to improve the distribution of the stripping agent and limit the vaporization of the stripping agent vapor from the target exhaust section, resulting in All of the above methods have high cost, difficulty in operation, and the like. The present inventors have discovered through a great deal of research that when a specific content is contained in tetrakis(β-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyloxymethyl)methane described in the above formula. When the bromine substance is compounded, the melt stability of the corresponding polymer container can be significantly improved.
