Norbornadiene is a bicyclic hydrocarbon and an organic compound. Norbornadiene is of interest as a metal-binding ligand, whose complexes are useful for homogeneous catalysis. It has been intensively studied owing to its high reactivity and distinctive structural property of being a diene that cannot isomerize (isomers would be anti-Bredt olefins). Norbornadiene is also a useful dienophile in Diels-Alder reactions.
Hydrogenated cycloolefin polymer having high adhesion and high elongation and method for preparing the same
The application relates to the technical field of high polymer materials, in particular to a hydrogenated cycloolefin polymer with high adhesion and high elongation and a preparation method thereof. The method comprises the following steps: performing a ROMP polymerization reaction on norbornadiene and a second cycloolefin in the presence of a solvent, a polymerization catalyst and a molecular weight regulator, obtaining a cycloolefin polymer solution after quenching; adding an oxidizing agent into the cycloolefin polymer solution to perform an opening ring oxidation reaction, and obtaining an intermediate after post-treatment; performing a hydrogenation reaction on the intermediate and hydrogen in the presence of a hydrogenation catalyst to obtain the hydrogenated cycloolefin polymer. The hydrogenated cycloolefin polymer provided by the application has higher elongation than conventional cycloolefin polymers, and has higher adhesion to glass and metal substrates.
