Synthesis of Polyketone by Copolymerization of Styrene and CO Using Carbon Nanotube-Complex Pd^2＋ Catalyst

The dipping method was devised to deposit Pd onto carbon nanotube as supported catalyst（Pd/CNT） for the copolymerization of carbon monoxide（CO） and styrene（ST） towards the formation of polyketone（PK）.The Pd/CNT was characterized by X-ray photoelectron spectroscopy（XPS）,X-ray diffraction（XRD） and hig...

description The dipping method was devised to deposit Pd onto carbon nanotube as supported catalyst（Pd/CNT） for the copolymerization of carbon monoxide（CO） and styrene（ST） towards the formation of polyketone（PK）.The Pd/CNT was characterized by X-ray photoelectron spectroscopy（XPS）,X-ray diffraction（XRD） and high-resolution transmission electron microscopy（HRTEM）.The construction and crystallization property of PK were evaluated by Fourier transform infrared spectroscopy（FTIR）,13C-nuclear magnetic resonance（NMR） and XRD,respectively.The catalyst showed excellent activity and reusability in promoting the fabrication of PK.It can be recycled 14 times with the highest total catalytic activity of 4 239.64 gPK/（gPd·h） at Pd content of 8.63wt%.The results indicate that the prepared catalyst is effective to catalyze the copolymerization of CO and styrene.
