Clay Encapsulation by Emulsion Polymerization

1 General Approaches in Encapsulation of Inorganic Particles (in General) by Emulsion Polymerization 

We first describe some general approaches to encapsulate inorganic particles other than clay by emulsion polymerization. Increased interest in this approach 

Usually, maximum properties can be obtained when the inorganic particles are distributed evenly and as single (primary) particles in the matrix. This means that in the steps towards obtaining the final product, keeping the particles well dispersed is of major importance. Initially the particles should be well dispersed in the aqueous phase and (partial) coagulation during the emulsion polymerization must be avoided because this leads to irreversible fixation of the coagulates.
