Previously a new method was introduced for the mass spectrometry of saturated polyolefins whereby an organic cation is covalently bonded to the polymer to produce the necessary ionization for the creation of intact gas-phase macromolecules by matrix-

Polyethylene and other polyolefins have not been amenable to mass spectrometric characterization of molecular mass distribution due to the ineffectiveness of conventional methods of cationization. The lack of polar groups, unsaturation, and aromatici

The density profiles of polymethylmethacrylate (PMMA) thin films on silicon (111) single crystal wafers were investigated via neutron reflectivity measurements. Films were prepared by spin casting PMMA onto silicon wafers from o-xylene solution follo
