CATIONIC CORE-SHELL PARTICLES WITH ACID-SWELLABLE SHELLS

摘要

The present invention about cationic core-shell particles there is sour insoluble polymer core and acid-swellable polymeric shell component to be generally arranged at around the core, so that a part of the shell is still attached or connected on the core in the shell and with sour. The present invention is further directed to polymer latex composition, wherein the polymer shell component has neutralized, and substantially (but not exclusively) in aqueous solution of the dissolution to form neutral core-shell polymer and mixture and shell polymeric. More particularly it relates to use the preparation cationic core-shell particles and formula of the latex composition thus prepared
