【期刊论文】Tailoring of polymer-supported metal catalysts for selective hydrogenation1

Several functional polystyrene-supported metal (Ru, Rh, Pd) catalysts were synthesized. The hydrogenation selec-tivity of these catalysts for polyunsaturated cycloolefines (1,5,9-cyclododecatriene, cyclopentadiene) and unsaturated carbonyl compounds (mesityl oxide, crotonaldehyde acrylic aldehyde) was investigated. Some important factors (pore size, crosslinkage of polymer supports, donor atoms and substituents thereon) for the tailoring of supports and ligands which have great influence over the hydrogcnation selectivity of the supported metal catalysts are discussed.

摘要

Ring-opening metathesis polymerization (ROMP) of dicyclopentadiene (DCPD) was carried out by using (ArO)6-xWClx-Et2A1C1 (ArO: 2,6-ditertiarybutyl-p-cresoxy, x=3, 4, 6) and the corresponding polymer-supported catalytic systems. Influences of different homogeneous catalysts, polymerization conditions and immobilization of the homogeneous catalytic systems on polymerization (gelation time, monomer conversion) and synthesized polydicyclopen-tadiene's (PDCPD's) mechanical properties were investigated. The experimental results show that using the polymer-supported catalytic systems can not only increase the monomer conversion of polymerization but also improve the synthesized polymer's mechanical properties to a certain extent.
