Modified Polysulfone Membranes. IV. Gas Separation with Aminated Polysulfone Membranes.

open access: yesSen'i Gakkaishi, 2000
Novel gas permeation membranes were prepared from polysulfones and amine-modified polysulfones. The introduction of the primary amine moiety into polysulfone membranes led to an increase in permselectivity toward CO2 in CO2/N2 separation and a significant increase in that toward O2 in O2/N2 separation.

Ultrafiltration of Milk: Effect on Lactoferrin, Lysozyme, and Lactoperoxidase Activity During Cheddar Cheese Ripening

open access: yesJournal of Food Process Engineering, Volume 49, Issue 8, August 2026.
The retention of lactoferrin lactoperoxidase, and lysozyme in milk concentrated by ultrafiltration (UF) before cheesemaking and on cheese properties was studied. Cheese made with concentrated milk retained 17% more LF than the control. No effect on cheese properties was observed. UF could be an additional tool to enhance cheese bioactivity.

Polyketones and polysulfones for conservation in the ethylene polymer market [PDF]

open access: yes, 1976
Because of the increase in cost of foreign oil, ethylene costs have increased markedly within the last several years. There is a sizable incentive to reduce raw material cost for basic polymer manufacture.

New approaches to design of blends based on quaternized polysulfones with optimized conductive properties [PDF]

open access: yes, 2017
New blends based on quaternized polysulfones, namely quaternized polysulfone/polyvinyl alcohol and quaternized polysulfone/cellulose acetate phthalate, were investigated in terms of their electrical properties.

Polysulfones with Phenylalanine Derivatives as Chiral Selectors – Membranes for Chiral Separation [PDF]

open access: yes, 2012
Polysulfone with a derivative of phenylalanyl residue as a chiral selector (PSf-Ac-D-Phe or PSf-Ac-L-Phe) were prepared by polymer reaction of benzylamine-modified polysulfones with N-a-acetyl-D-phenylalanine or N-a-acetyl-L-phenylalanine.
