Then NH 4 2 S 2 O 8 MBA and TMEDA were successively dispersed into the solution. Monomers were purified by distillation under reduced pressure. Polyacrylic acid Powder Mw 450000 PAA 450K CAS Number.
Polyacrylic acid PAA is a non-toxic biocompatible and biodegradable polymer that gained lots of interest in recent years. For example nano-particles produced from PAA derivatives can be used to deliver drugs. Polyacrylic acid PAA or Carbomer is generic name for synthetic high molecular weight polymers of acrylic acid.
Differences in the PPO content in Pluronics L92 and F127 result in a higher hydrophobicity of the resulting L92-PAA-EGDMAmicrogels and a larger presence of hydrophobic densely cross-linked clusters that aggregate into supramolecular structures rather than micelle-like aggregates such as those formed in the F127-PAA-EGDMA microgels. Cozens et al 2021. Polyacrylic Acid PAA Polymer Properties.
The hydrogels were crosslinked on the polytetrafluoroethylene PTFE mold under. Polyacrylic acid is innoxious. Polyacrylic Acid PAA is used as scale inhibitor and dispersant for circulating cool water.
