Acrylic emulsion polymers are widely used in the adhesive industry as solvent-free pressure sensitive adhesive polymers. However, in order to achieve a wider range of performance on more difficult-to-stick-to substrates, formulating the emulsion polymer with tackifiers becomes necessary. This work demonstrates how an unconventional zwitterionic emulsion polymerization chemistry can be used for synthesizing a stable tackifier-containing acrylic emulsion polymer.
