1. A frontally polymerized polymeric body comprising:
a deformable polymer comprising polydicyclopentadiene (pDCPD) and/or poly(5-ethylidene-2-norbornene) (pENB), the deformable polymer having a fracture strain of at least 0.5 mm mm−1,
wherein the deformable polymer is prepared by frontal polymerization from a first resin formulation comprising: dicyclopentadiene (DCPD) and/or 5-ethylidene-2-norbornene (ENB) at a DCPD:ENB volume ratio in a range from 0:100 to 100:0; and more than one ruthenium catalyst.
