Description

Description: TECHNICAL FIELD The present invention relates to a polyphenylene ether resin composition having excellent hollow moldability and a molded article produced therefrom.

(Prior art) Polyphenylene ether has a glass transition temperature of 210 to 220.
It has high heat resistance of as high as ° C. and becomes amorphous once melted, so that it has a characteristic of good dimensional accuracy. However, the molding processability and chemical resistance are inferior, so that they are not suitable for producing injection-molded products and hollow-molded products by themselves.

On the other hand, polyamide has a high melting point and a high glass transition temperature, has a low melt viscosity and good chemical resistance, and is therefore widely used in injection molding. However, since polyamide has a low melt tension, parison drawdown during hollow molding is severe, and it is difficult to obtain a single large hollow product. At present, it is used for multi-layer extrusion with high-density polyethylene having a large melt tension and used for imparting gas barrier properties to products.

In recent years, many attempts have been made to obtain polymer alloys having the characteristics of polyphenylene ether and the characteristics of polyamide. For example, JP-A-56-47432,
As described in JP-A-56-49753 and JP-A-57-36150, polymer alloys for injection molding having improved mechanical properties, heat resistance and chemical resistance of both are provided. ing. However, it has been found that even if these are used for hollow molding, the drawdown is large as described above, and the uneven thickness is large, so that it is not practical.

(Problems to be Solved by the Invention) The present invention significantly improves parison drawdown characteristics in hollow molding while having good quality in mechanical properties, heat resistance, and chemical resistance like these polymer alloys. It is intended to improve. This allows
Polyphenylene ether, which is effectively used for parts of automobile outer panels, fuel tanks, oil tanks, radiators, duct hoses, harness tubes, air spoilers, bumpers, side protectors, seats, rear shelf and other housings or chemical bottles The purpose is to provide a resin composition.

(Means for Solving the Problems) The present invention is a polyphenylene ether resin composition comprising the following components, having a melt flow rate (MFR) of 0.01 to 5 dg / min and a melt tension (MT) of 4 g or more.

(A) Intrinsic viscosity [η] measured in chloroform at 30 ° C.
Is from 0.35 to 0.75 dl / g in the range of polyphenylene ether (B) relative viscosity ηr (measured in JIS K6810,98% sulfuric acid)
Is a polyamide having a value of 2.5 or more. (C) Impact modifier (D) Compatibilizer and (E) Ethylenically unsaturated silane compound-modified polyolefin polymer <Component> (A) Polyphenylene ether Used in the present invention Polyphenylene ether has the general formula: Wherein Q is independently hydrogen, halogen, a hydrocarbon group having no tertiary α-carbon atom, or halo in which a halogen atom is substituted through at least two carbon atoms. A hydrocarbon group, a hydrocarbonoxy group, and a monovalent substituent selected from the group consisting of a halohydrocarbonoxy group in which a halogen atom is substituted through at least two carbon atoms, wherein each Q is the same as each other, May also be different.

Also, a copolymer of 2,6-diethylphenol and 2,3,6-trimethylphenol, 2,6-dimethylphenol and
Copolymer with 2,3,5,6-tetramethylphenol, 2,6-
Copolymers such as a copolymer of dimethylphenol and 2,3,6-trimethylphenol can also be mentioned.

Further, the polyphenylene ether used in the present invention also includes modified polyphenylene ethers such as those obtained by grafting a styrene monomer (for example, styrene, p-methylstyrene, α-methylstyrene, etc.).

Processes for producing polyphenylene ethers corresponding to the above are known and are described, for example, in U.S. Pat.
No. 75, No. 3257357 and No. 3257358, as well as JP-B Nos. 52-17880 and JP-A-50-51197.

The polyphenylene ether used in the present invention has a temperature of 30 ° C.
Has an intrinsic viscosity [η] of 0.35 to 0.3 as measured in chloroform.
Those in the range of 75 dl / g are preferred. If the intrinsic viscosity is less than 0.35 dl / g, the impact strength of the composition is poor, which is not preferable. On the other hand, those having an intrinsic viscosity of more than 0.75 dl / g are not preferable because the gel content is large and the appearance of the molded article is deteriorated.

(B) Polyamide The polyamide used in the present invention is hexamethylenediamine, decamethylenediamine, dodecamethylenediamine, 2,2,4- or 2,4,4-trimethylhexamethylenediamine, 1,3- or 1,4-bis (aminomethyl) cyclohexane, bis (p-aminocyclohexylmethane),

The polymerization degree is usually a polyamide having a relative viscosity (η) of 2.5 or more (JISK6810, measured in 98% sulfuric acid).
If it is 2.5 or less, the melt flow rate (MFR) becomes 5 dg / min or more, and the molded product is undesirably reduced. Those having a relative viscosity of 4.0 or more are preferable because the draw-down of the molten parison is small and a medium or large product having a parison length exceeding 1 m can be formed stably.
