Abstract
The present invention relates to a method for the polymerization of cycloolefins by ring-opening metathesis. The reaction is carried out in the presence of at least one particular catalyst, selected from the ruthenium alkylidene complexes comprising at least one 1-aryl-3-cycloalkyl-imidazolin-2-ylidene ligand and mixtures thereof. The invention also relates to a kit for implementing this method.
Claims17
A method for the polymerization of cycloolefins by ring-opening metathesis, comprising contacting at least one cycloolefin, optionally functionalized, with at least one metathesis catalyst selected from the ruthenium alkylidene complexes comprising at least one 1-aryl-3-cycloalkyl-imidazolin-2-ylidene ligand, in effective conditions for polymerizing said at least one cycloolefin,
- wherein said at least one cycloolefin is cyclopentadiene, cyclopentadiene oligomers, mixtures of cyclopentadiene and cyclopentadiene oligomers, mixtures of cyclopentadiene and at least one other optionally functionalized cycloolefin selected from:
- norbornene, norbornadiene, dicarboxylic norbornene anhydride, cyclohexene, cycloheptene, cyclooctene, cyclododecene and cyclooctadiene, mixtures of cyclopentadiene oligomers and at least one other optionally functionalized cycloolefin selected from:
- norbornene, norbornadiene, dicarboxylic norbornene anhydride, cyclohexene, cycloheptene, cyclooctene, cyclododecene and cyclooctadiene, or a mixture of cyclopentadiene, cyclopentadiene oligomers and at least one other optionally functionalized cycloolefin selected from:
- norbornene, norbornadiene, dicarboxylic norbornene anhydride, cyclohexene, cycloheptene, cyclooctene, cyclododecene and cyclooctadiene.
