This work is focused on the synthesis of aqueous polymeric dispersions based on
polyvinyl acetate and sucrose formed by emulsion polymerization technique. These
polymeric latexes can be used in the field of sustained release fertilizer
encapsulation or as ecological paper glue with the subsequent biological disposal.
The main objective of the work was to bond covalently sucrose into polyvinyl
acetate ensuring the effective biodegradation of the respective polymer mainly in
the soil environment. We have searched for an optimal ratio between the polymer
and the simple sugar in the alkaline medium so that the resulting latex could
exhibit good water solubility, sufficient bond strength, and the stability of
atmospheric humidity. Using infrared spectroscopy, the process of binding
sucrose into the polymer chain of vinyl acetate has been demonstrated.
