Synthesis and characterization of acrylic composite thickener microgels through inverse emulsion polymerization with novel crosslinking method

These days, thickener microgels have numerous applications. However, despite of their various advantages, inappropriate physical properties are considered as their flaws. In this study, composite thickener microgels based on Acrylic Acid (AA), Sodium Acrylate (NaA) and Cloisite 30B nanoparticles were produced through inverse emulsion polymerization (IEP).In this paper, a novel crosslinking method was introduced for composite microgels preparation. Diglycidyl materials were used instead of vinyl crosslinkers for composite microgel preparation. Composite microgels were characterized by viscosity measurement and rheometrical analysis. Produced composite microgels have higher thickening capability and mechanical strength respect to common microgels produced without presence of nano particles
