Propene-cycloolefin polymerization
Highly active metallocenes and other single site catalysts have opened up the possibility of polymerizing cycloolefins such as norbornene (N) or of copolymerizing them with ethene (E) or propene (P). The polymers obtained show exciting structures and properties. E-N copolymers are industrially produced materials, with variable and high glass transitions depending on the wide range of their micr...

متن کاملImmobilization of biomolecules on cycloolefin polymer supports.
Recent trends in the development of microfluidic and biodiagnostic chips favor polymer materials over glass, primarily for optical and economical reasons. Therefore, existing chemical methods to prepare biomolecule microarrays on glass slides have to be adapted or replaced in order to suit polymer substrates. Here we present a strategy to immobilize DNA and antibodies on cyclic polyolefin slide...
متن کاملSynthesis of fluorinated chitin derivatives via enzymatic polymerization.
Synthesis of fluorinated chitin derivatives has been achieved using chitinase from Bacillus sp. as a catalyst. 6'-Fluoro- (1a), 6-fluoro- (1b) and 6,6'-difluoro- (1c) chitobiose oxazoline derivatives were newly prepared as TSAS monomers for chitinase. Ring-opening polyaddition of these monomers proceeded effectively at pH 8.0-9.0 and 30-40 degrees C, giving rise to alternatingly 6-fluorinated c...
