METHOD OF MAKING A POLYMER ARTICLE AND RESULTING ARTICLE

摘要

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.
