Abstract: Disclosed herein is a composition comprising a cationically polymerizable first epoxide and a second epoxide. The first epoxide is a glycidyl epoxide and the second epoxide further comprises a glycidyl epoxide and/or a non-glycidyl epoxide. The disclosed composition further comprises an initiator and a filler, where the composition upon external stimulus undergoes an ionic polymerization reaction in a spatially propagating reaction front or in a global reaction that occurs throughout an entire composition.

Abstract: 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.

Abstract: Disclosed herein is a foam composition comprising a first epoxide comprising a first glycidyl epoxide and/or a first non-glycidyl epoxide; a second epoxide comprising a second glycidyl epoxide and/or a second non-glycidyl epoxide; wherein the first glycidyl epoxide is different from the second glycidyl epoxide and wherein the first non-glycidyl epoxide is different from the second non-glycidyl epoxide; wherein the first and the second epoxide are cationically polymerizable; an initiator; and a diluent; wherein the diluent is present in about 0.1 to 30 wt %, based on the total weight of the composition; wherein the composition upon external stimulus undergoes an ionic polymerization reaction in a spatially propagating reaction front or in a global reaction that occurs throughout an entire composition.
