Synthesis and 13C-NMR analysis of an ethylene copolymer with 9-decen-1-ol

2015 
Copolymerization of ethylene with 9-dencen-1-ol (9D1O) was conducted by using Cp*Ti(O-2,6-iPr2C6H3)Cl2 and Me2Si(Me4Cp)(NtBu)TiCl2 as catalysts. The catalysts and the polymerization conditions strongly affected the activity, molecular weight of the polymer, and the incorporation of 9D1O. The incorporation of 9D1O is as high as 13.6 mol%. The assignments of the 13C-NMR spectra and analysis of the sequence distribution showed that the microstructure of the polymer was also highly dependent on the catalysts and the polymerization conditions. The results also indicated that the effect of the hydroxyl group of 9D1O on the polymerization was fully reduced by the methylene spacers.
