Stable emulsion polymers and methods of preparing same |
摘要 |
The present invention provides for a process for producing a stabilized latex characterized by the steps of: a) mixing latex forming monomers, under emulsion polymerization conditions to form a hydrophilic, low molecular weight, first stage polymer reaction mixture capable of becoming water soluble upon pH adjustment; b) contacting said reaction mixture containing the first stage polymer with latex forming monomers under emulsion polymerization conditions sufficient to form a second stage hydrophobic polymer which forms an invert core-shell emulsion with said first stage polymers and c) adjusting the pH of the emulsion to dissolve the first stage polymer, as well as the latex produced thereby. o |
