Probing the Interactions between Mimics of Pour Point Depressants (PPDs) and Viscosity Index Improvers (VIIs) in Engine Oil Using Fluorescently Labeled PPDs
Gholami, Kiarash; Jiang, Sheng; Duhamel, Jean (American Chemical Society, 2019-03-18)The level of interpolymeric interactions experienced by a pyrene-labeled poly(octadecyl methacrylate) labeled with 6.7 mol% of 1-pyrenebutanol (Py(6.7)-PC18MA) was characterized by fluorescence in the presence of an amorphous ... -
Quantifying the Level of Intermacromolecular Interactions in Ethylene-Propylene Copolymers by Using Pyrene Excimer Formation
Pirouz, Solmaz; Duhamel, Jean; Jiang, Sheng; Duggal, Akhilesh (American Chemical Society, 2015-07-14)A unique methodology based on fluorescence measurements is introduced to quantitatively measure the actual level of interpolymeric association between ethylene-propylene (EP) copolymers used as viscosity index improvers ...
