  • Curable compositions
    Patent number: 11591493
    Abstract: Heterocyclic-functional resins, such as epoxides, oxetanes, cyclic carbonates, lactides and lactones, are used in radiation-curable formulations along with ethylenically unsaturated materials such as (meth)acrylates to achieve improved mechanical properties and/or lower shrinkage in the cured compositions prepared therefrom as compared to formulations containing the ethylenically unsaturated materials but no heterocyclic-functional resin. Polymerizable, ethylenically unsaturated metal complexes, such as Zn and Ca carboxylates prepared using unsaturated carboxylic acids or anhydrides, may be employed to effect thermal cure of the heterocyclic-functional resin component of such formulations, which are particularly useful in the production of 3D-printed articles and the like.
