Problems solved by technology

More specifically, it is described that a linear oligomer (a hydroxyl oligomer at both ends consisting of 4 units of a benzene ring component and a fluorine-based oligomer at both ends consisting of 5 units of a benzene ring component) represented by the above formula is obtained. Cyclic poly(phenylene ether ketone) is only composed of cyclic 3-mer (m=3) and cyclic 6-mer (m=6), which are respectively cyclic poly(phenylene ether ketone) with melting points of 366°C and 324°C. In some cases, there is a problem that thermoplastic resins that can be used as resin modifiers are limited.
[0007] On the other hand, Patent Document 1 discloses a composition in which a low-viscosity polyarylene ether ketone resin is added as a viscosity modifier to a higher-viscosity polyarylene ether ketone resin. The polyarylene ether ketone resin only exemplifies chain polyarylene ether ketone, and there is no description about the effect of adding cyclic polyarylene ether ketone. Insufficient effect of viscosity modifiers like poly(arylene ether ketone)
In addition, Patent Documents 2 to 6 disclose resin combinations in which a small amount of polyether ether ketone resin is added to high heat-resistant thermoplastic resins such as aromatic polyamide, polyetherimide, polyphenylene sulfide, and liquid crystal polyester. However, they all add chain poly(arylene ether ketone), and there is no description about the effects and characteristics of adding cyclic poly(arylene ether ketone) to thermoplastic resins.

Abstract

A thermoplastic resin composition is provided having excellent flowability, high crystallization characteristics, high transparency and excellent processability in melt processing to resin molded products, sheets, films, fibers and pipes. The thermoplastic resin composition includes 100 parts by weight of (A) a thermoplastic resin; and 0.5 to 50 parts by weight of (B) a cyclic poly(phenylene ether ketone) that is expressed by General Formula (I) given below and has phenylene ketone shown by -Ph-CO- and phenylene ether shown by -Ph-O- as are repeating structural unit: wherein Ph in Formula represents a para-phenylene structure; o and p are respectively integral numbers of not less than 1; and m is an integral number of 2 to 40.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition, which provides excellent fluidity, high crystallization characteristics, and transparency by blending a cyclic polyphenylene ether ketone mixture having a specific ring structure, and is used in resin molded articles, sheets, and films. A thermoplastic resin composition excellent in processability during melt processing of fibers, tubes, and the like. Background technique [0002] Thermoplastic resins, especially engineering plastics excellent in mechanical properties and heat resistance, are used in various applications due to their excellent properties. For example, polyamide resins and polyester resins are used in various electrical and electronic parts, mechanical parts, and automotive parts mainly for injection molding because of their excellent balance between mechanical properties and toughness. Butylene phthalate (hereinafter referred to as PBT) and polyethylene terephthalate ...
