    Abstract: 本发明涉及一种高阻隔水蒸汽聚酯薄膜及其制备方法,将改性聚酯按照制膜工艺制得高阻隔水蒸汽聚酯薄膜;改性聚酯的制备方法为:将对苯二甲酸、乙二醇、2,5-吡啶二甲酸和氯化镍混合均匀后先后进行酯化反应和缩聚反应得到改性聚酯;制得的聚酯链段包括对苯二甲酸链段、乙二醇链段和2,5-吡啶二甲酸链段,且不同聚酯链段的2,5-吡啶二甲酸链段的之间经Ni 2+配位;对苯二甲酸链段和2,5-吡啶二甲酸链段的摩尔比为1:0.08~0.10;2,5-吡啶二甲酸链段参与配位的有一个羰基上的O原子和吡啶上的N原子。本发明通过Ni 2+与2,5-吡啶二甲酸配位减少了自由体积,使得聚酯薄膜水蒸汽的阻隔性得到提高,高阻隔水蒸汽聚酯薄膜在38℃、90%相对湿度条件下的水蒸汽透过率≤1.0g/(m 2·d)。

    Abstract: A water- and oil-repellent composition comprises (a) a repellency-imparting, fluorochemical composition comprising at least one fluorine-containing aromatic ester oligomer comprising (1) at least two repeat units derived or derivable from the reaction of at least one dicarboxylic acid (or a derivative thereof) and at least one polyol, with the proviso that either the dicarboxylic acid (or derivative) or the polyol (or both) is aromatic or heteroaromatic, and (2) fluorochemical endgroups derived or derivable from the reaction of (i) the dicarboxylic acid (or derivative) and at least one fluorine-containing monoalcohol, or (ii) the polyol and at least one fluorine-containing monocarboxylic acid; and (b) a treatable substrate; with the proviso that, when the treatable substrate comprises a mixture of at least two polymers, the mixture is non-stratifying.
