2. Description of the Related Art Polyethylene terephthalate has been widely applied as a packaging material because of its excellent physical properties (mechanical strength, moldability, storability of contents). However, the gas barrier property is not sufficient for the contents that are very susceptible to oxygen, or the contents that are easily deteriorated due to the loss of carbon dioxide gas and aroma components. There is known a method of blending a saponified product of an ethylene-vinyl acetate copolymer, which has excellent properties.

Blending is generally carried out by melt mixing using a single screw or the like, and then the melt blended product is formed into a film by a suitable device or formed into a biaxially stretched bottle. However, since the compatibility of polyethylene terephthalate and the saponified product of ethylene-vinyl acetate copolymer is not sufficient, blending causes deterioration of physical properties of materials, particularly mechanical properties such as impact strength and flexibility, making them unsuitable for practical use.

When the weight ratio of the saponified ethylene-vinyl acetate copolymer in the blend is increased, the physical properties decrease as the ratio increases.
Up to about 0% by weight, the physical properties are not significantly different from those of polyethylene terephthalate alone, but when it exceeds 20% by weight, the physical properties are remarkably deteriorated and the composition is very brittle, which makes practical use difficult. Therefore, the improvement of the gas barrier property of polyethylene terephthalate by blending a saponified product of ethylene-vinyl acetate copolymer can be performed only in a range in which the mechanical properties of the material are not significantly deteriorated, which is not sufficient.

When the ethylene content is less than 20 mol%, the thermoplastic moldability is poor, and when it is 60 mol% or more, the effect of improving the gas barrier performance is small. Polyethylene terephthalate (A)
The blending weight ratio of the saponified ethylene-vinyl acetate copolymer (B) is preferably in the range of A: B = 90: 10 to 10:90. When the blending ratio is outside this range, the physical properties of the blended substance are close to each other, the blending effect is not exhibited, the physical properties of the blended product are not significantly deteriorated, and the physical property improving effect by adding the compatibilizer is small.

The amount of the reactive resin composition added is preferably 5 to 40 parts by weight with respect to the blend of the polyethylene terephthalate and the saponified product of the ethylene-vinyl acetate copolymer. If the addition amount is 5 parts by weight or less, the compatibility improving effect becomes insufficient, and if the addition amount is 40 parts by weight or more, the ratio of the reactive functional group contained in the reactive resin composition in the blend increases, so that heat molding is performed. The thermal stability becomes worse.

The reactive resin composition added as a compatibilizing agent to the blended product of the polyethylene terephthalate and the saponified product of ethylene-vinyl acetate copolymer is 0.5 to 10 mol of a vinyl monomer containing a reactive functional group. % Of the polyolefin-based copolymer contained is 10 to the copolymer.
Those grafted with 50% by weight of polar group-containing vinyl polymer are suitable. An epoxy group or an acid anhydride can be used as the reactive functional group, and the content in the copolymer is preferably 0.5 to 10 mol%. If it is 0.5 mol% or less, the compatibility improving effect is insufficient, and if it exceeds 10 mol%, the thermal stability during melt blending is lowered.

As the olefin component of the polyolefin copolymer, ethylene is generally used, and if necessary, other monomer components such as olefin, acryl and vinyl may be contained. The polar group-containing vinyl polymer grafted to the polyolefin copolymer may be polymethylmethacrylate, and is preferably 10 to 50% by weight based on the copolymer. 1
If it is 0% by weight or less, the dispersion of the reactive resin composition as a compatibilizer becomes poor and the compatibility improving effect becomes insufficient.
If it is more than 10% by weight, the proportion of reactive functional groups in the reactive resin composition decreases, and the effect of improving the compatibility also decreases.

The blending operation for preparing the resin composition is carried out by pre-mixing pelletized polyethylene terephthalate, ethylene-vinyl acetate copolymer saponification product, and reactive resin composition in a predetermined ratio, and then mixing the mixture with a single screw extruder. It may be melt-mixed using a twin-screw extruder or the like, and then the melt is formed into a film by using a T-die as necessary,
It is possible to mold it into a container shape by axial stretch molding. It is also possible to once form the melt blend into pellets and use this as a material. Further, the blended resin composition can be used by being compounded with other materials, and can be applied in multiple layers for the purpose of imparting a gas blocking function to a base material such as polyolefin.
