摘要： Disclosed is a process for the preparation of shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles, having high transparency and low haze comprising immiscible blends of one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enables the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce shaped articles having oxygen-scavenging properties.

摘要： Disclosed is a process for the preparation of multilayered, shaped articles having high transparency and low haze having at least one layer contains one or more thermoplastic polymers selected from polyesters, polycarbonates, and homogeneous blends thereof, and a separate layer which contains a transamidized, homogeneous blend of a least two polyamides. The thermoplastic polymer components and the polyamide components have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enable the incorporation of regrind into one or more of the layers of the article while maintaining high clarity. These articles can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into one or more layers to impart oxygen-scavenging properties.

摘要： Disclosed is a process for the preparation of multilayered, shaped articles having high transparency and low haze and in which at least one layer contains at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol and a separate layer which contains a transamidized, homogeneous blend of a least two polyamides. The polyester component and the polyamide component have refractive indices which differ by about 0.006 to about −0.0006. The small difference in the refractive indices enable the incorporation of regrind into one or more of the layers of the article while maintaining high clarity. These articles can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into one or more layers to impart oxygen-scavenging properties.
摘要翻译： 公开了一种制备具有高透明度和低雾度的多层成型制品的方法，其中至少一层包含至少一种包含2,2,4,4-四甲基-1,3-环丁二醇的聚酯和分开的层 其包含至少两种聚酰胺的酰胺化均匀共混物。 聚酯组分和聚酰胺组分的折射率相差约0.006至约-0.0006。 折射率的小差异使得可以将再研磨物掺入制品的一层或多层中同时保持高透明度。 这些制品可以表现出改进的优异的阻隔性能和良好的熔融加工性，同时保持优异的机械性能。 可以将金属催化剂并入一个或多个层中以赋予氧气清除性能。
