摘要： The invention includes a copolymer of vinylidene chloride with at least one monounsaturated comonomer and at least one branching monomer in an amount sufficient to increase molecular weight over that of a polymer prepared using the same process and same monomers in the same relative amounts except without the branching monomer, but preferably the branching monomer is present in a quantity not sufficient to result in measurable crosslinking as determined by solubility in tetrahydrofuran at up to 83 °C. The invention includes a process for making the polymer and processes for forming the copolymer or compositions thereof as well as articles comprising the copolymer and compositions thereof. The copolymer exhibits improved bubble stability and is particularly useful for processes in which the copolymer is at least partially oriented in formation such as blow molding, formation of monofilament fiber and film blowing.
摘要翻译：本发明包括偏二氯乙烯与至少一种单不饱和共聚单体和至少一种支化单体的共聚物，其量足以增加分子量超过使用相同方法制备的聚合物的分子量和相同相同量的相同单体，除了不含支链单体，但是优选支化单体的存在量不足以导致可测量的交联，其通过在高达83℃下在四氢呋喃中的溶解度测定。本发明包括制备聚合物的方法和形成共聚物或其组合物的方法以及包含共聚物及其组合物的制品。共聚物表现出改善的气泡稳定性，并且特别适用于其中共聚物在形成中至少部分取向的方法，例如吹塑，单丝纤维的形成和吹膜。
