[Industrial Application Field] The present invention relates to a polycarbonate resin composition that has improved solvent resistance and moldability while maintaining the impact resistance and transparency of the polycarbonate resin. [Prior Art] Polycarbonate resins have conventionally been known as molding resins that have excellent physical properties such as impact resistance and thermal properties. However, the polycarbonate resin has a high melt viscosity, and therefore the molding temperature and molding pressure are high compared to other resins, which is considered to be a difficult point in molding. Furthermore, polycarbonate resin molded articles not only have poor hardness, but also have the disadvantage of being susceptible to cracking when subjected to concentrated stress in the presence of certain solvents. It has been proposed that various polyesters be blended with polycarbonate resin in order to improve the poor moldability and solvent resistance, which are disadvantages of polycarbonate resin, without significantly impairing the excellent physical properties and heat resistance inherent in polycarbonate resin. has been done. For example, a composition in which polyalkylene terephthalate, which is a copolymerization of a difunctional carboxylic acid component and a diol component having a large amount of aromatic rings, is blended with a polycarbonate resin (Japanese Patent Publication No. 57-16137,
No. 54-37633, Japanese Patent Application Laid-open No. 50-102648) have been proposed. However, since this composition has a high aromatic content in the diol component to improve transparency, it has drawbacks such as fading during molding, and is also economically disadvantageous because the diol component is expensive. It is. Also known is a composition in which a polyalkylene terephthalate containing cyclohexanedimethanol as a diol component is blended with a polycarbonate resin (Japanese Patent Application Laid-open No. 94536/1983), but since this polyalkylene terephthalate is amorphous, it is resistant to solvents. There are disadvantages in that the improvement in properties is insufficient and the composition is colored, which limits its uses. However, the present invention maintains the excellent impact resistance and transparency of polycarbonate resin, while improving solvent resistance and
The purpose of the present invention is to provide a polycarbonate resin composition with excellent transparency after heat treatment. [Means for Solving the Problems] As a result of intensive research to achieve the above object, the present inventors have found that a resin composition in which a polyester resin containing a specific diol component is blended with a polycarbonate resin has extremely excellent properties. The present invention was completed based on the discovery that the composition has the following properties and that adding a partial ester to this composition further improves moldability, thermal stability, etc. That is, the first aspect of the present invention provides a composition comprising 90 to 10% by weight of a polycarbonate resin (A) and 10 to 90% by weight of a polyester resin (B) consisting of a bifunctional carboxylic acid component and a diol component.

A polycarbonate resin composition characterized by comprising 99 to 70 mol% of alkylene glycol, and the second invention is a polycarbonate resin composition characterized by comprising 99 to 70 mol% of alkylene glycol. This is a polycarbonate resin composition characterized by containing ~1.0% by weight. The polycarbonate resin used in the present invention has the following general formula: (Here, Z is a bond, or alkylene having 1 to 8 carbon atoms, alkylidene having 2 to 8 carbon atoms, or 5 carbon atoms.
~15 cycloalkylene, C5-15 cycloalkylidene, SO 2 , SO, O, CO or R means a hydrogen, chlorine or bromine atom or a saturated alkyl group having 1 to 8 carbon atoms, and m represents a number from 0 to 4. It is a polymer having a structural unit represented by This polycarbonate resin is prepared by a solvent process, i.e., by reaction of dihydric phenol with a polycarbonate precursor such as phosgene or by reaction of dihydric phenol with a polycarbonate precursor such as phosgene in a solvent such as methylene chloride in the presence of known acid acceptors, molecular weight modifiers, etc. It can be produced by transesterification with a carbonate precursor such as carbonate. Here, dihydric phenols that can be suitably used include bisphenols, and 2,2-bis(4-hydroxyphenyl)propane (bisphenol A) is particularly preferred. In addition, bisphenol A
may be partially or entirely replaced with other dihydric phenols. Examples of divalent phenols other than bisphenol A include hydroquinone, 4,4'-dihydroxydiphenyl, bis(4

Compounds such as hydroxyphenyl) sulfide, bis(4-hydroxyphenyl) sulfone, bis(4-hydroxyphenyl) sulfoxide, bis(4-hydroxyphenyl) ether or bis(3,5-dibromo-4- Examples include halogenated bisphenols such as hydroxyphenyl)propane and bis(3,5-dichloro-4-hydroxyphenyl)propane. These dihydric phenols may be homopolymers or copolymers or blends of two or more dihydric phenols. Furthermore, the polycarbonate resin used in the present invention may be a thermoplastic randomly branched polycarbonate obtained by reacting a polyfunctional aromatic compound with a dihydric phenol and/or a carbonate precursor. From the viewpoint of mechanical strength and moldability, the polycarbonate resin used in the present invention preferably has a viscosity average molecular weight of 10,000 to 100,000, particularly
20,000 to 40,000 is suitable. The resin composition of the present invention is formed by blending 10 to 90% by weight of a specific polyester resin with the above-mentioned polycarbonate resin. If the amount of polyester resin blended is less than 10% by weight, the solvent resistance of the resin composition will be insufficient, and if it exceeds 90% by weight, the impact resistance of the resin composition will be greatly reduced, which is unsuitable. The amount of polyester resin blended is preferably 10 to 60% by weight. The polyester resin used here has the following general formula consisting of a bifunctional carboxylic acid component and a diol component. (In the formula, Ar is an aromatic hydrocarbon group, Z is a divalent group, and n is a number from 1 to 30.) It is a polyester resin mainly composed of aromatic dicarboxylate units. The intrinsic viscosity of this polyester resin is usually 0.4 to 1.5 dl/g, preferably 0.5 to 1.5 dl/g.
It is 1.2dl/g. Examples of the difunctional carboxylic acid component include aromatic dicarboxylic acids such as terephthalic acid, isophthalic acid, and naphthalene dicarboxylic acid. Among these, terephthalic acid is preferred, and other difunctional carboxylic acid components may be used in combination within a range that does not impair the effects of the present invention. They are, for example, oxalic acid,
Aliphatic dicarboxylic acids such as malonic acid, adipic acid, suberic acid, azelaic acid, sebacic acid or decanedicarboxylic acid, and ester-forming derivatives thereof. The blending ratio of these other dicarboxylic acid components is generally 20% by mole based on the total dicarboxylic acids.
within Further, as the diol component, a specific aromatic diol and alkylene glycol are used in combination. The specific aromatic diol used in the present invention has the following general formula: (In the formula, X is -CH 2 O-, -C 2 H 4 O- or -
