  • A PROCESS FOR PREPARING CORE-SHELL PARTICLES HAVING A POLYMER CORE AND A CONTINUOUS SILICA SHELL, AN AQUEOUS POLYMER DISPERSION OBTAINABLE BY SAID PROCESS, A REDISPERSIBLE POLYMER POWDER, AND A COMPOSITION COMPRISING THE REDISPERSIBLE POLYMER POWDER
    Publication number: 20190119453
    Abstract: The invention relates to a process for preparing core-shell particles having a polymer core and a continuous silica shell. The in situ formed core-shell architecture suppresses film formation of the polymer and simplifies the subsequent drying process.
