High solid content (HSC) latexes are of growing interest for many reason, but making this type of product entails many difficulties. Increasing the solid content (fraction of polymer relative to the continuous phase) in a reproducible manner entails the strict control of a complex particle size distribution (PSD). The PSD must be either quite broad, or multimodal in order to obtain solids contents much above 55 or 60 vol%. In addition, the viscosity of a latex is highly sensitive to the PSD near the upper limit of solids content; however, it is still not possible to predict a priori how a complex PSD will effect the viscosity. This article presents an overview of the rheology of concentrated latexes, followed by a discussion of the state of the art in the area of high solids latex production.

An approach to prepare high solids content latexes ( รบ50 wt %) is presented. The approach is based on a two-stage polymerization where in the first stage low-tomedium solids content seed latexes with a broad particle-size distribution (PSD) were prepared by semicontinuous miniemulsion polymerization
## Abstract **Summary:** A novel polymerization procedure to synthesize latex stabilized by alkaliโsoluble resin (ASR) is detailed. According to this process, latexes with a high solid content and low viscosity are obtained using a substantially lower amount of ASR when compared with existing techn
