ROMP of norbornene catalysed by Grubbs functionalized carbon nanotubes
نویسندگان
چکیده
The synthesis of polynorbornene by ring opening metathesis polymerization (ROMP) in the presence of 1 2 generation Grubbs catalyst-functionalized nanotubes, is reported. A characterization of the 2 generation Grubbs catalystfunctionalized nanotubes was performed by TGA (Thermogravimetric Analysis) on-line connected with a quadrupole-mass spectrometer, in order to quantify the amount of catalyst grafted to the nanotube surface. The activities of the catalyst-functionalized nanotubes in ROMP of 2-norbornene were compared with those of pure 2 generation Grubbs catalysts.

متن کاملSynthesis of Poly(norbornene-methylamine), a Biomimetic of Chitosan, by Ring-Opening Metathesis Polymerization (ROMP)
ROMP is an effective method for preparing functional polymers due to its having characteristics of "living" polymerization and rapid development of catalysts. In the present work, poly(norbornene-methylamine), a mimic of chitosan, was synthesized via ROMP reaction. The amino-protected product, 5-norbornene-2-(N-methyl)-phthalimide, was prepared by a reaction of 5-norbornene-2-methylamine with p...

Described herein is the efficient synthesis and evaluation of bioactive arginine-glycine-aspartic acid (RGD) functionalized polynorbornene-based materials for cell adhesion and spreading. Polynorbornenes containing either linear or cyclic RGD peptides were synthesized by ring-opening metathesis polymerization (ROMP) using the well-defined ruthenium initiator [(H(2)IMes)(pyr)(2)(Cl)(2)Ru═CHPh]. ...

Nanoparticles containing fluorine-18 were prepared from block copolymers made by ring opening metathesis polymerization (ROMP). Using the fast initiating ruthenium metathesis catalyst (H2IMes)(pyr)2(Cl)2Ru=CHPh, low polydispersity amphiphilic block copolymers were prepared from a cinnamoyl-containing hydrophobic norbornene monomer and a mesyl-terminated PEG-containing hydrophilic norbornene mon...

New phenoxybenzylidene ruthenium chelates were synthesised from the second generation Grubbs catalysts bearing a triphenylphosphine ligand (or its para-substituted analogues) by metathesis exchange with substituted 2-vinylphenols. The complexes behave like a latent catalyst and are characterized by an improved catalytic behaviour as compared to that of the known analogues, i.e., they exhibit hi...
