Patent

CA 2613687

The invention provides a method of preparing a crosslinked polymer, which method comprises polymerising branched polyunsaturated monomers by a metathesis polymerisation reaction, wherein the branched polyunsaturated monomers contain acyclic ethylenically unsaturated groups that are capable of undergoing polymerisation by a metathesis reaction such that the metathesis polymerisation produces a crosslinked polymer and substantially no non- volatile ethylenically unsaturated by-products.

La présente invention fournit un procédé de préparation d~un polymère réticulé, lequel procédé comprend la polymérisation de monomères polyinsaturés ramifiés par une réaction de polymérisation de type métathèse, les monomères polyinsaturés ramifiés contenant des groupes acycliques éthyléniquement insaturés qui sont capables de subir une polymérisation par l~intermédiaire d~une réaction de métathèse de telle sorte que la polymérisation de type métathèse produise un polymère réticulé et pratiquement pas de sous-produits éthyléniquement insaturés non-volatiles.
