Application

  • IR and Raman investigation of some poly(acrylic) acid gels in aqueous and neutralized state: This study explores the modification of local polymeric conformation of poly(acrylic) acid (PAA), induced by hydration and neutralization with triethanolamine, using IR and Raman spectroscopy. (M Todica et al., 2015).
  • Phase Behavior of Aqueous Poly(acrylic acid-g-TEMPO): Research on poly(acrylic acid) grafted with TEMPO moieties, focusing on phase separation behavior over different pH ranges, which could be relevant for creating responsive materials. (Q Fu et al., 2016).
  • Synthesis and characterization of poly(glyceric acid carbonate): a degradable analogue of poly(acrylic acid): This article presents a degradable analogue to poly(acrylic acid) and compares the properties of hydrogels prepared from this new polymer with those from PAA, relevant for biomedical applications. (H Zhang et al., 2015).
  • Mechanically stable thermally crosslinked poly(acrylic acid)/reduced graphene oxide aerogels: Study on enhancing the mechanical integrity of reduced graphene oxide aerogels by intermixing with thermally cross-linkable PAA, pertinent to material science. (H Ha et al., 2015).
  • Polyacrylic acid polymers hydrogels intended for topical drug delivery: preparation and characterization: Investigates the bioadhesiveness of polyacrylic acid polymers in hydrogels, emphasizing their potential in designing topical drug delivery systems. (G Calixto et al., 2015).

A novel galactose-decorated cross-linked micelles (cl-micelles) with ionic cores using cystamine (Cys) as a biodegradable cross-linker was prepared by using block ionomer complexes of poly(ethylene glycol)-b-poly(2-acryloxyethyl-galactose)-b-poly(acrylic acid) (PEG-b-PAEG-b-PAA) and Ca(2+) (PEG-b-PAEG-b-PAA cl-micelles/Cys). Doxorubicin (DOX) was successfully incorporated into the ionic
