Enzymatic polymerization.

nzymatic polymerization is emerging as a scalable process to polymerize sucrose into engineered polysaccharides. Polymer archi-tecture and material properties can be controlled selectively to provide the foundation for novel differentiated biomaterial platforms. One first example for such an engineered polysaccharide is alpha-1,3-polyglucose (alpha-1,3-glucan), which was prepared using this bioprocess. This article describes initial results applying this polymer in architectural coating applications. With the ability to control polysaccharide particle mor-phology, crystallinity, as well as overall polymer functionality and particle size, it was envisioned that polysaccharides can be designed to provide performance advantages for paint applications.
