Abstract:
1. A process for producing a component for producing polymer blends from thermoplastic starch and a hydrophobic polymer, the method comprising the steps of: a) providing an aqueous dispersion of polyvinyl acetate; b) adding a catalyst, selected from the group consisting of mono-hydroxy compounds, dihydroxy compounds, and trihydroxy compounds, to the aqueous dispersion; c) presaponifying the aqueous dispersion of polyvinyl acetate by adding an alkaline substance to the aqueous dispersion; d) providing an alkali silicate solution; e) reacting in a batch mixer the presaponified polyvinyl acetate of step c) with the alkali silicate solution of step d) by adding, while stirring, the alkali silicate solution to the presaponified polyvinyl acetate of step c) over a period of at least one hour to form organosilicates, wherein a combined water contents of the presaponified polyvinyl acetate and of the alkali silicate solution is greater than 40%.
