Artificial neural networks (ANNs) are a useful tool for the prediction of the particle size (PS), polydispersity index (PDI), and encapsulation efficiency (EE) of phenolic compounds (PC) in nanosystems because they consider the effects of all independent variables. This is very important for the prediction of the PS, PDI, and EE of nanosystems produced

DOLLAR G(A)-FLUOROACRYLIC POLYMERS WITH LOW POLYDISPERSITY INDEX
2003The invention concerns alpha -fluoroacrylic polymers comprising more than 50 % by weight of recurrent alpha -fluoroacrylic units, and whereof the polydispersity index (Mw/Mn) is more than 1.50. The invention also concerns an alpha -fluoroacrylic monomer radical polymerization method involving brominated and/or iodinated and/or chlorinated initiator ...

In the polymer industry, product quality is usually determined by the molecular weight distribution of polymer products. We propose a comprehensive study of polymer product design through dynamic optimization of average molecular weights and the polydispersity index in batch free radical polymerization.

Journal of Polymer Science Part B: Polymer Physics, 1991
AbstractA novel chromatographic method is proposed to determine the polydispersity index, without reference to standards, for polymers that contain a specified number of functional groups. Refractive index and ultraviolet‐visible (or infrared) detectors are employed for detecting the weight and number fractions, respectively, of the sample eluted in ...
