Field Flow Fractionation for the Size, Molar Mass, and Gel Content Analysis of Emulsion Polymers for Water-Based Coatings

Autor: Harald Pasch, Ryan P. Williams, Ashwell C. Makan

Publikováno v: Macromolecular Chemistry and Physics. 217:2027-2040

In the present investigation, styrene-acrylic and pure acrylic emulsions used in water-based decorative coatings are characterized by size exclusion chromatography (SEC) and asymmetric flow field-flow fractionation (AF4). Both the separation techniqu

Advanced analysis of polymer emulsions: Particle size and particle size distribution by field-flow fractionation and dynamic light scattering

Autor: Harald Pasch, Markus J. Spallek, Ashwell C. Makan, Madeleine du Toit, Thorsten Klein

Publikováno v: Journal of Chromatography A. 1442:94-106

Field flow fractionation (FFF) is an advanced fractionation technique for the analyses of very sensitive particles. In this study, different FFF techniques were used for the fractionation and analysis of polymer emulsions/latexes. As model systems, a

Analysis of High Molar Mass Branched Polybutadienes by SEC-MALLS and AF4-MALLS

Autor: T. Otte, Ashwell C. Makan, Harald Pasch

Publikováno v: Macromolecules. 45:5247-5259

Industrial polybutadienes synthesized by Ziegler–Natta catalysts may exhibit very high molar masses, significant degrees of branching, and gel species. Such samples were analyzed by size exclusion ...

Comparison of Two Doses of Intravenous Dexmedetomidine as Premedication for Laryngeal Mask Airway Insertion in Adults: A Randomised Clinical Trial

Autor: Rachel Botelho, Shirley Ann Dsouza, Anisha Deulker, Ashwell Correia, Sherin Mathews

Publikováno v: Journal of Clinical and Diagnostic Research, Vol 15, Iss 12, Pp 20-24 (2021)

Introduction: The Laryngeal Mask Airway (LMA) has gained popularity in recent years for both rescue ventilation as well as airway management device for General Anaesthesia (GA). Adequate jaw relaxation and blunting of airway reflexes prevents hae

Analysis of complex polymers by multidetector field-flow fractionation

Autor: Wolf Hiller, Nyashadzashe Ngaza, Helen Chirowodza, Harald Pasch, Ashwell C. Makan

Publikováno v: Analytical and bioanalytical chemistry. 406(6)

Field-flow fractionation (FFF) is a powerful alternative to column-based polymer fractionation methods such as size-exclusion chromatography (SEC) or interaction chromatography (IC). The most common polymer fractionation method, SEC, has its limitati

Asymmetrical flow field-flow fractionation as a novel technique for the analysis of PS-b-PI copolymers

Autor: Pritish Sinha, Harald Pasch, Werner van Aswegen, Nyashadzashe Ngaza, Ashwell C. Makan

Publikováno v: Analytical and bioanalytical chemistry. 405(28)

Asymmetrical flow field-flow fractionation (AF4) was used as a fractionation technique to investigate the molecular heterogeneity of poly(styrene-b-isoprene) diblock copolymers synthesized by either sequential living anionic polymerization or couplin
