The catalyst is particularly useful for isomerizing 5-vinyl-2-norbornene to 5-ethylidiene-2-norbornene.
Suitably said norbornene group is present as an amino acid residue of a norbornene lysine.
The top layer comprises a co-polymer that comprises, in polymerized form, norbornene or a norbornene derivative.
The present invention concerns a method for the preparation of norbornene and substituted norbornene compounds via a Diels-Alder reaction, in which method a cyclic diene is reacted with an olefinic compound in order to prepare a norbornene compound.
Ethylene, norbornene, and cyclooctene are copolymerized.
The present invention relates to a method for producing 5-norbornen-2-carboxylic acid from 5-norbornen-2-endo-carbonitrile and/or 5-norbornen-2-exo-carbonitrile.
Embodiments in accordance with the present invention encompass polymers having at least one norbornene-type repeating unit derived from a norbornene-type monomer having a polyhedral oligosilsesquioxane pendant group.
The present invention relates to a norbornene based addition polymer, and more particularly to an addition polymer of norbornene based monomers containing an ester group.
and in particular copoly(ethylene/norbornene) blocks and (ethylene/propylene/ethylidenenorbornene) block terpolymers.
Preferably said aryl-substituted cyclic monomer is phenyl-norbornene (5-phenyl-bicyclo-2,2,1-hept-2-ene) or indanyl-norbornene (1,4-methano-1,4,4a,9a-tetrahydrofluorene).
Therefore, the present invention provides addition copolymers of cyclic olefins of norbornene type compounds and norbornene type compounds containing sulfur, and methods for preparing the same.
The present invention relates to a norbornene polymer that comprises a norbornene monomer having a photoreactive functional group, and a method of manufacturing the same.
The invention relates to an odorant for city gas, containing norbornene or a norbornene derivative, a thinner and optionally additional additives.
A retardation film containing a norbornene copolymer.
Also disclosed is a process for producing the norbornene compound.
and in particular copoly(ethylene/norbornene) blocks and (ethylene/propylene/ethylidene-norbornene) block terpolymers.
The norbornene based polymers can be used as a solid substrate for forming the necessary features for a microfluidic device, where the entire may be made of norbornene based polymer.
This invention provides a norbornene- ester polymer, obtaining by a norbornene- ester monomer having a total number of carbons of the ranges from 19 to 80, having a bulky substituent.
The cycloolefin polymer is preferably an ethylene-norbornene copolymer.
A particularly preferred macromonomer comprises a terminal norbornene functional group.
