Title: (EN) Methods for preparing transparent formed articles comprising polymer containing a cyclobutanediol
(ZH) 含有包括环丁二醇的聚酯的透明成形制品的制备方法
Abstract:
(EN) 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, and comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-l ,3-cyclobutanediol, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend 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 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.

本发明公开了用于制备成形制品如片材、薄膜、管道、瓶子、预成型件和轮廓的方法,所述制品具有高的透明度和低的浊度,并且包括至少一种包含2,2,4,4-四甲基-1,3-环丁二醇的聚酯以及共聚酰胺或聚酰胺的均匀掺合物的不溶混掺合物。所述不溶混掺合物组分间的折射率差为约0.006到约-0.0006。折射率差小使得能够向聚合物组合物中加入再生物以产生透明的成形制品。这些制品可以具有显示出改进的优秀阻隔性能和良好的熔融加工性能,同时保持优秀的机械性能的一层或多层。可以向所述组合物中加入金属催化剂以产生具有除氧特性的成形制品。
