Preparation of heterogeneous film from core-shell composite polymer particles produced by the stepwise heterocoagulation method with heat treatment

Abstract

Core-shell composite polymer particle consisting of a hydrophilic core and hydrophobic shell was produced by the stepwise heterocoagulation of small cationic styrene-butyl acrylate-methacryloyoxyethyl trimethylammonium chloride terpolymer particles onto a large anionic methyl methacrylate-ethyl acrylate-methacrylic acid terpolymer particle (LP), which was proposed by the authors in 1990. In order to prepare a film from such a core-shell composite polymer emulsion, the shell content was controlled by changing the diameter of LP and by increasing the methacrylic acid content in LP.
