Provided are dual cure monomer are of the formula: (I) wherein R* is a (hetero)hydrocarbyl group; X 1 is —O—, —S—, —NR 3 —, —NR 3 —CO—NR 3 , —CO—NR 3 — or NR 3 —CO—, where R 3 is H, C 1 -C 4 alkyl or R 1 -Epoxy; R 1 is a divalent (hetero)hydrocarbyl group; X 2 is —O—, —S—, —NR 4 —, —NR 4 —CO—NR 4 —, —CO—NR 4 —, —NR 4 —CO— where R 4 is H, C 1 -C 4 alkyl or R 2 —CH═CH 2 ; R 2 is a divalent (hetero)hydrocarbyl group; subscripts a and b are at least one, subscripts c and d are at least one, with the proviso that the monomer has at least two epoxy groups and at least two ene groups. |
