More Information
Summary:wherein n is an integer between 0 and 100, and wherein each R is independently selected from aromatic and aliphatic groups which contain between 1 and 24 carbons and which are optionally substituted, typically comprising 0.1-20% by weight of the polycarbodiimide. In some embodiments the present disclosure provides sheet materials made of such cured, uncured or partially cured materials. In some embodiments these compositions may be useful in making surfacing films for composite parts and may demonstrate good paint stripper resistance and microcrack resistance.
