  The present invention relates to a method comprising the steps of a) contacting under emulsion polymerization conditions vinyl acetate; a cyclic ketene acetal monomer; and a monoethylenically unsaturated acid monomer or a salt thereof; to form an aqueous dispersion of copolymer particles comprising structural units of vinyl acetate, the cyclic ketene acetal, and the monoethylenically unsaturated acid monomer or a salt thereof; wherein the cyclic ketene acetal monomer is characterized by following structure: where n and the R groups are as defined herein. The method of the present invention provides a water-borne dispersion that is substantially free of volatile organic solvents and that provides a readily degradable polymer that is useful, for example, in the manufacture of biodegradable packaging products.

  本发明涉及一种方法，包括以下步骤 a) 在乳液聚合条件下，将乙酸乙烯酯、环己酮缩醛单体和单乙烯基不饱和酸单体或其盐接触，形成共聚物颗粒的水分散液，共聚物颗粒由乙酸乙烯酯、环己酮缩醛和单乙烯基不饱和酸单体或其盐的结构单元组成；其中环己酮缩醛单体的结构特征如下： 其中 n 和 R 基团如本文所定义。本发明的方法提供了一种水性分散体，该分散体基本上不含挥发性有机溶剂，并提供了一种易降解聚合物，可用于制造生物可降解包装产品等。
