Claim 13:
14. A partially cured precursor of a structural adhesive composition, comprising:
a polymeric material comprising the self-polymerization reaction product of a polymerizable material comprising a cationically self-polymerizable monomer which comprises at least one cyclic amine
optionally, some residual polymerization initiator of the cationically self-polymerizable monomer which is initiated at a temperature T1;
a curable monomer which is different from the cationically self-polymerizable monomer which comprises at least one epoxy group; and
a curing initiator of the curable monomer which is initiated at a temperature T2 and which is different from the polymerization initiator of the cationically self-polymerizable monomer; and
wherein the curable monomers are substantially uncured and are in particular embedded into the polymeric material comprising the self-polymerization reaction product of a polymerizable material comprising a cationically self-polymerizable monomer.
