Polymer viscosity‐molecular weight distribution correlations via blending: for high molecular weight poly (dimethyl Siloxanes) and for polystyrenes

EM Friedman, RS Porter - Transactions of the Society of Rheology, 1975 - pubs.aip.org
The correlation between low‐shear Newtonian melt viscosity and polymer molecular weight
distribution in the high molecular weight region is inspected via the viscosity of homologous …

NIR chemical imaging to guide/support BMS-561389 tablet formulation development

…, CJ Pommier, SIF Badawy, EM Friedman - International journal of …, 2008 - Elsevier
The objective of this study was to determine whether the particle size of extra-granular
tartaric acid affects the uniformity of its distribution within BMS-561389 tablets. A near-infrared …

Nematic-Like Flow Behavior in a Non-Steroid Cholesteric Mesophase

EM Friedman, RS Porter - Molecular Crystals and Liquid Crystals, 1975 - Taylor & Francis
Steady flow viscosity data were obtained on a compound which exhibits a cholesteric liquid
crystalline mesophase but does not contain the steroid moiety. The compound is (+)-2-methyl…

Modality of molecular weight distributions

EM Friedman - Polymer Engineering & Science, 1990 - Wiley Online Library
Even restricting attention to weight distributions, it is ambiguous to merely say that a polymer
is “not bimodal.” A simple example is shown wherein the weight distribution of log …

[PDF][PDF] In-process microbial testing: Statistical properties of a rapid alternative to compendial enumeration methods

EM Friedman, M Warner, SC Shum… - PDA Journal of …, 2015 - scholar.archive.org
In-process tests are used between manufacturing steps to avoid the cost of further processing
material that is apt to fail its final tests. Rapid Microbiological Methods (RMM’s) that return …

Challenges and opportunities in implementing the FDA default parametric tolerance interval two one-sided test for delivered dose uniformity of orally inhaled products

…, H Strickland, M Golden, HJ Delzeit, EM Friedman - AAPS …, 2011 - Springer
The goal of this article is to discuss considerations regarding implementation of the parametric
tolerance interval two one-sided test (PTI-TOST) for delivered dose uniformity (DDU) of …

Effect of a Choleresteric Texture on X-ray Diffraction Patterns from Liquid Crystalline Polypeptides

EM Friedman, RJ Roe - Molecular Crystals and Liquid Crystals, 1974 - Taylor & Francis
Calculation is made of the effect on the X-ray diffraction pattern obtainable when a cholesteric
twist is superimposed on the otherwise ordered packing of rod-like molecules. Reflections …

Stability models for sequential storage

EM Friedman, SC Shum - AAPS PharmSciTech, 2011 - Springer
Some drugs are intended for sequential storage under two different storage conditions. If the
data for each condition are analyzed separately, predicting assay and other responses after …

High‐conversion emulsion polymerization in a continuous reactor: Predictions using smith–ewart kinetics

EM Friedman - Journal of Polymer Science: Polymer Physics …, 1980 - Wiley Online Library
Smith–Ewart Case‐2 kinetics are applied to a continuous stirred tank reactor operating at
steady state in the high and middle range of conversion. Above the conversion C D at which …
