Abstract
Saturated hydrocarbon polymers, polyethylene, polypropylene and their derivatives, are the most widely used of all synthetic polymers. Their chemical structure and composition, molecular mass (MM), and molecular?mass distribution (MMD) are critical in determining performance properties. The potential for quick and direct measurement of single-chain composition and MMD makes mass spectrometry (MS) especially attractive to the polymer industry. However, using MS analysis for the determination of MMDs requires the formation of intact macromolecular ions in the gas phase, which has proven quite difficult for saturated polyolefins due to the lack of a suitable ionizable site on the aliphatic chain. The present study demonstrates the feasibility of using eta- 5-cyclopentadienylcobalt ion (CpCo +) as cationization reagent for saturated hydrocarbon analysis.Citation
