Classification: CPC C | IPC C

Claim 14:
15. A method for producing the crosslinked polymeric composition of claim 1, the method comprising reacting the following components:
A molecules:, , wherein G is a hydrocarbon linkage connected to at least E1 and E2 and optionally to one or both of E3 and E4, if present, wherein E1, E2, E3, and E4 are epoxy groups;
B molecules:, , wherein M is a hydrocarbon linkage connected to at least I1 and I2 and optionally I3, if present, wherein I1, I2 and I3 represent isocyanate groups;
C molecules:, , wherein L1 and L2 are independently hydrocarbon linkers, and V1 and V2 are independently functional groups reactive with epoxy groups (E1, E2, E3, and E4 groups) and isocyanate groups (I1, I2, and I3 groups);
wherein:
dashed bonds represent optional bonds;
V1 and V2 react with E1 and E2, and optionally E3 and/or E4, if present, to produce first linking units having the formula:, , wherein J is a linkage resulting from reaction between an epoxy group, selected from E1, E2, E3, and E4 groups, and a group reactive with an epoxy group, selected from V1 and V2 groups, to result in said first linking units covalently bonding between G hydrocarbon linkages of A molecules and L1 and L2 of C molecules; and
V1 and V2 react with I1 and I2, and optionally I3, if present, to produce second linking units having the formula:, , wherein K is a linkage resulting from reaction between an isocyanate group, selected from I1, I2, and I3 groups, and a group reactive with an isocyanate group, selected from V1 and V2 groups, to result in said second linking units covalently bonding between M hydrocarbon linkages of B molecules and L1 and L2 of C molecules.
