Monomers and composition which can be crosslinked and crosslinked polymers |
| PATENT ABSTRACT |
Compounds of the formula I (A).sub.n --B (I) in which A is the radical of a strained cycloolefin, B is a direct bond or an n-valent bridging group and n is an integer from 2 to 8, with the exception of 1,2-bisnorbornenyl-ethane and norbornenecarboxylic acid norbornenemethyl ester. The compounds of the formula I can be polymerized with one-component catalysts (ring-opening metathesis polymerization). |
