In this Study, two types of polymerization processes are used; batch and semi-batch. Sampeles
were prepared by using long-chain acrylate crosslinker and acrylic acid monomer via precipitation
polymerization. The effect of batch and semi-batch process on different features of microgel (i.e.,
equilibrium swelling, gel content, and apparent viscosity) was investigated. This result shows that
the type of process affects very strongly on the formation of cross-links in network and network
properties. Since, the apparent viscosity of PAA-PE-550 by semi-batch process was highest even
though the viscosity of PAA–PE-550 by batch process was least.
