| titleOfInvention | Encapsulated hydrophilic polymer and preparation method thereof |
| abstract | A multistage polymer is disclosed that contains a hydrophilic core completely encapsulated in a hydrophobic shell without a tiecoat layer.n n n (a) about 5-100% by weight of hydrophilic monoethylenically unsaturated monomer based on the total weight of the core polymer and 0-about 95% by weight of at least one nonionic monoethylenically unsaturated monomer based on the total weight of the core polymer Emulsion polymerizing the polymer; (b) about 0.1-9 acid-functional monoethylenically unsaturated monomer based on the total weight of about 90-99.9% by weight of the shell polymer, in the presence of the core polymer, at least one nonionic monoethylenically unsaturated monomer based on the total weight of the shell polymer Emulsion-polymerizing at least one shell polymer of -10% by weight, wherein the acid-functional monoethylenically unsaturated monomer is a total shell when the size of the core polymer particles is about 130 nm to about 2.0 microns Also provided is a method for encapsulating a hydrophilic polymer, characterized in that it is added upon shell polymer polymerization over 100% of the monomer feed and if the size of the core polymer particles is less than about 130 nm.n n n The method according to the invention for encapsulating a hydrophilic polymer with a hydrophobic polymer does not require a tiecoat layer. |
