Influence of Hydroxyl Group Concentration on Mechanical Properties and Impact Resistance of ROMP Copolymers

Ring-opening metathesis polymerization (ROMP) produced homopolymers and copolymers of 5-ethylidene-2-norbornene (ENB) and 5-methanol-2-norbornene (NBOH), and this provided a platform to explore the influence of monomer polarity and noncovalent interactions on the mechanical and high velocity impact performance. The tensile yield, mode-I fracture, and high velocity impact behavior displayed a strong dependence on the hydroxyl-containing NBOH...
