Polymaleimide-Based Polysulfobetaines Bearing Functional and Nonfunctional Hydrophobic Units and Its Aggregation Behavior in Aqueous Media
Langmuir, 2019
Dsouza, R.F., Parthiban, A.
Copolymaleimide based zwitterionic polysulfobetaines (PM-SBs) were prepared by a "top down" method for the first time. Interfacial studies of these polymers showed many interesting characteristics. These PM-SBs did not require any salt in t...

Synthesis of amine-functionalized block copolymers for nanopollutant removal from water
Journal of Applied Polymer Science, 2014
Qureshi, Z.S., Dsouza, R., Mallampati, R., Valiyaveettil, S.
ABSTRACTPolyamines are rare in literature owing to increased reactivity, sensitivity to air and moisture, low stability, and processing difficulties. Here, we report the synthesis and characterization of highly processable polyamines and us...
