摘要： Provided is a polyester composite film, comprising a first thermoplastic polyether ester elastomer (TPEE) film and a second TPEE film. The melting point of a second TPEE resin of the second TPEE film is higher than that of a first TPEE resin of the first TPEE film, and the absolute difference in enthalpy of fusion between the first and second TPEE films is 5 J/g to 15 J/g. By adopting the first and second TPEE films having specific absolute difference of the enthalpy of fusion and controlling the melting points of the first and second TPEE resins, the polyester composite film can be well attached onto the fabric by hot pressing to obtain sufficient peel strength, and thereby the attached fabric can have excellent waterproof performance. Besides, a hot melt adhesive laminate comprising the polyester composite film also exhibits the above beneficial effects when attached to the fabric.

The cured oxygen-absorbing adhesive agent resin composition preferably includes: (A) an oxygen-absorbing polyester resin having a glass transition temperature of −20 to 10° C. and (B) a saturated polyester resin having a glass transition temperature of −10° C. or lower. The oxygen-absorbing polyester-based resin (A) is made from a tetrahydrophthalic acid, a derivative thereof, a tetrahydrophthalic anhydride, or a derivative thereof, and the saturated polyester resin (B) containing a structural unit derived from a diol component and a structural unit derived from a dicarboxylic acid component is preferably selected from the group consisting of adipic acid, sebacic acid, isophthalic acid, and combinations thereof.

摘要： The present invention relates to a semi-crystalline mixture of polyester polyols which recrystallises upon melting and which can be obtained by polycondensing a reaction mixture comprising one or more dicarboxylic acids selected from saturated aliphatic dicarboxylic acids having an even number of at least 8 methylene groups, and one or more diols selected from aliphatic diols which have at least one ether function. The invention also relates to a polymeric material which is obtained from the chemical modification of the mixture of polyester polyols with organic compounds which contain at least one isocyonate group and/or epoxide group. The mixtures and materials according to the invention are characterised by relatively low melting enthalpies, while the melting temperature can be set in a range of −30 to 60° C., meaning that it is possible to obtain easily fusible formulations containing the mixtures and materials according to the invention. The mixtures and materials according to the invention also provide such formulations with a high elasticity and breaking resistance. The present invention therefore includes the use of the polyester polyols and polymeric materials according to the invention as deforming, fusing, and extrusion means in thermoplastic materials, and the use thereof for producing adhesives and sealants, in particular hot-melt adhesives and reactive adhesives.

As a result, they found a heat-sealable polyester resin which can be used for food application and which exhibits excellent adhesiveness to various containers made of polystylene, polyvinyl chloride, A-PET (amorphous polyethylene terephthalate) , or polypropylene, each having different property.
The aim of the present invention is to provide a polyester resin which exhibits excellent adhesiveness to various substrates such as polystylene, polyvinyl chloride, or A-PET.
According to the present invention, there is provided a polyester resin containing a polycarboxylic acid component and a polyhydric alcohol component as constitution units, wherein, when the total amount of the polyhydric alcohol component is taken as 100 mol%, the content of diethylene glycol component is 60 mol% or more, and wherein the glass transition temperature of the polyester resin is 20° C. or lower.
