Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermoplastic resin composition which has high rigidity and high heat resistance, significantly reduces burrs generated during molding, and is excellent in moldability and impact resistance.

[0002]

2. Description of the Related Art Polyarylene sulfide resin is a thermoplastic resin having excellent heat resistance, chemical resistance, electric properties, mechanical properties, dimensional stability, etc.
It is used as a sealing material for electronic components. However, since this resin is a highly crystalline polymer, it exhibits extremely high fluidity in a temperature range exceeding the melting point. For this reason, there is a problem that it is difficult to control the fluidity at the time of injection molding, burrs are generated on the molded product, and the yield of precision molded products is significantly reduced. Conventionally, attempts to improve the moldability by blending another thermoplastic resin with a polyarylene sulfide resin have been known (JP-B-53-13469, JP-A-2-180945, JP-A-2-180945, -28
No. 1564, Japanese Unexamined Patent Publication No. 6-306287), it cannot be suppressed to such an extent that the occurrence of burrs during molding does not pose a practical problem.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the prior art, and has been developed in consideration of the above-mentioned problems, and it is intended to maintain the physical properties (high rigidity and high heat resistance) of a polyarylene sulfide resin while maintaining the burr during molding. It is an object of the present invention to provide a thermoplastic heat-resistant resin composition which is excellent in molding processability and impact resistance.

[0004]

According to the present invention, (a) 40 to 98% by weight of a polyarylene sulfide resin, (b) 60 to 1% by weight of a norbornene resin and (c) 60 to 1% by weight of a polyphenylene ether resin are used. It is intended to provide a thermoplastic resin composition containing the same.

BEST MODE FOR CARRYING OUT THE INVENTION

(A) component; (a) polyarylene sulfide resin,
The main structural unit is a general formula; -Ar-S- (wherein, Ar
Represents a divalent aromatic, and S is a sulfur atom). Examples of the divalent aromatic constituting the polyarylene group include p-phenylene group, m-phenylene group, 2,6-naphthalene group, 4,4′-biphenylene group, p, p′-bibenzyl group, and these. And the like, as a typical example. Of these,
Poly-p-phenylene sulfide (PPS) having a nucleus-unsubstituted p-phenylene group is preferred from the viewpoint of moldability. In the present invention, it is necessary that the polyarylene sulfide resin (a) contains at least 70 mol% of the above structural units in one molecule. If this constituent unit is less than 70 mol%, undesired results such as a decrease in the crystallinity of the obtained polyarylene sulfide resin, a low glass transition temperature, and poor physical properties of the molded product are produced. In the present invention, (a) the polyarylene sulfide resin is less than 30 mol% in one molecule,
Aromatic group having a bond of three or more valences, for example, 1,2,2
It may contain a 4-bonded phenylene nucleus, an aliphatic group, a hetero atom-containing group, and the like. Further, the terminal group of the polyarylene sulfide resin (a) is not particularly limited, but preferably contains at least 80 mol% of a thiol group (SH group). Further, (a)
As the polyarylene sulfide resin, a linear type, a semi-crosslinked type, and a crosslinked type can be used alone or in combination according to the purpose.

Further, as the polyarylene sulfide resin (a), a modified polyarylene sulfide resin or a mixture of a modified polyarylene sulfide resin and a polyarylene sulfide resin can be used. As the modified polyarylene sulfide resin, a resin modified with a functional group such as an epoxy group, an amino group, a carboxyl group, an acid anhydride group, an oxazoline group, a vinyl group, an acryloyl group, a methacryloyl group, an isocyanate group, and a mercapto group Can be used, and an epoxy group-modified polyarylene sulfide resin and an amino group-modified polyarylene sulfide resin are particularly preferable. These functional groups are reacted with an ester in the (b) norbornene-based resin to form a block copolymer of a polyarylene sulfide resin and a norbornene-based resin, thereby increasing the compatibility between the two and resulting resin composition. Of the polyarylene sulfide resin, and the anisotropy of the physical properties and moldability, which are disadvantages of the polyarylene sulfide resin, can be reduced. The method for producing the polyarylene sulfide resin (a) includes a condensation reaction of a dihalogenated aromatic compound and a diol aromatic compound, a condensation reaction of a monohalogenated aromatic thiol, or a dihalogenated compound and an alkali sulfide or a hydrosulfide. A method utilizing a desalination condensation reaction of an alkali and an alkali or hydrogen sulfide and an alkali compound is exemplified, but the method is not limited thereto.

In the present invention, (a) the viscosity of the polyarylene sulfide resin is usually from 100 to 4,000 at a temperature of 300 ° C. and a strain rate of 1,000 sec ^-1 .
Poise. (A) The amount of the polyarylene sulfide resin to be blended is preferably 40% in the components (a) to (c).
%, More preferably from 60 to 97% by weight, even more preferably from 70 to 95% by weight. From the characteristics of the obtained resin composition, if the amount is less than 40% by weight, the heat resistance of the resin composition may decrease, while if it exceeds 98% by weight, burrs may be remarkably generated.

Component (b): The (b) norbornene-based resin of the present invention is a polymer derived from a specific monomer represented by the following general formula (1).
Is included. Ring-opening polymer of specific monomer Ring-opening copolymer of specific monomer and copolymerizable monomer Hydrogenated polymer of the above ring-opening (co) polymer Free of the above ring-opening (co) polymer Hydrogenated copolymer after cyclization by Delkraft reaction Saturated copolymer of specific monomer and unsaturated double bond-containing compound
