Adhesives based on carbodimide chemistry

Described herein is a thermosetting resin composition, obtained from the reaction of at least: a polycarbodiimide (i), where the number of carbodiimide groups per molecule is in the range of from 1 to 10; a mixture of crystalline and amorphous polyols (ii), where the molar ratio of carbodiimide grou...

Beschreibung
Zusammenfassung:	Described herein is a thermosetting resin composition, obtained from the reaction of at least: a polycarbodiimide (i), where the number of carbodiimide groups per molecule is in the range of from 1 to 10; a mixture of crystalline and amorphous polyols (ii), where the molar ratio of carbodiimide groups in the polycarbodiimide according to (i) to hydroxyl groups in the mixture according to (ii) is in the range of from 1:2 to 2:1 and where at least 25 weight-% of the mixture according to (ii) consists of at least one crystalline polyesterol, based on the overall weight of the mixture being 100 weight-%. Also described herein is a method of using the thermosetting resin composition as an adhesive, as well as processes for preparation of adhesives, an element including an adhesive layer on at least one substrate, and an adhesive film, obtained from one of the processes.
