Disclosed are degradable materials including molded products, laminates, foams, pellets, nonwoven materials, adhesives, coatings and films, and particularly packaging films. The materials are made using polydioxaneone polymers comprising at least two different dioxaneone-based repeating units. Preferred polymers are polydioxanediones. First repeating units have less carbon atoms in constituent groups extending from the polymer backbone than second repeating units. Physical characteristics and degradation of the materials can be varied by varying the choice and/or relative proportions of first and second repeating units in the polydioxaneone polymers.
所公开的可降解材料包括模塑产品、层压板、泡沫塑料、颗粒、无纺布材料、粘合剂、涂层和薄膜,尤其是包装薄膜。这些材料使用聚
二噁烷酮聚合物制成,该聚合物至少包含两种不同的
二噁烷酮重复单元。首选聚合物是聚二氧杂
环戊烯。与第二种重复单元相比,第一种重复单元从聚合物骨架延伸出来的组成基团中的碳原子数较少。可通过改变聚二氧杂
环戊酮聚合物中第一和第二重复单元的选择和/或相对比例来改变材料的物理特性和降解性。
