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: 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.
