Abstract: FLUORINATEDCORE -SHELL -POLYMERS AND PROCESS FOR PREPARING SAME Disclosed is a process for preparing fluorinated core-shell polymer particles in which the core is a non-fluorinated polymer and the shell is derived from at least % by weight of fluorinated monomers, by 1 ) synthesizing a core polymer latex by aqueous emulsion polymerization of non-fluorinated monomers forming the core polymer, 2) adding the shell-forming fluorinated monomers or mixtures of at least 50% by weight of fluorinated monomers with non-fluorinated monomers to the core polymer latex of step 1 ) and allowing for at least one hour of equilibration time in which essentially no polymerization of the shell monomers occurs, 3) reacting the shell- forming monomers in the mixture from step 2) to form the core-shell polymer particles, wherein the process steps 1 ) to 3) are carried out under mechanical stirring in the absence of surfactants, emulsifiers, emulsifying monomers and mixtures thereof. No suitable figure.
