A method of making a polymer article comprises the steps of making a polymer solution by mixing a first compound containing carbodiimide groups with a second compound containing carboxylated groups, applying the polymer solution to a former, wherein the step of applying occurs within 2 hours of the making of the polymer solution, and curing the polymer solution. The polymer solution can have a pH adjuster consisting of ammonium hydroxide.
一种制造聚合物制品的方法包括以下步骤:通过将含有碳二
亚胺基团的第一种化合物与含有羧基的第二种化合物混合制成聚合物溶液;将聚合物溶液涂抹在成形器上,其中涂抹步骤在制成聚合物溶液后 2 小时内完成;以及固化聚合物溶液。聚合物溶液中可加入由氢氧化
铵组成的 pH 调整剂。
