Impact of polymer tacticity on the physico-chemical behaviour of polymers proposed as therapeutics

open access: yes, 2011
Although water-soluble polymers are finding increasing use as polymer therapeutics, there has been little consideration of the effect of polymer stereochemistry on their physico-chemical and biological properties. The aim of this study was to investigate

Modified Polysaccharides in Laundry Applications as Soil Release and Anti‐Redeposition Additives

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 22, June 10, 2025.
ABSTRACT Polymers play an important role within modern laundry formulations, enhancing their cleaning performance by aiding in the release of soil from textiles and helping to prevent soil resettling upon the textiles during washing. Most of these polymers are derived from non‐renewable petrochemical sources; however, a combination of factors ...
