Abstract With styrene (St), butyl acrylate (BA), and methyl methacrylate (MMA) as monomers, a core-shell structure was utilized to synthesize a polymerization emulsion. Then, self-crosslinked polyacrylic acid emulsions with different crosslinking degrees were synthesized by changing the amount of DAAM using deception acrylamide (DAAM) and adipic acid dihydrazide (ADH) as functional monomers. The basic performance tests demonstrated that the inclusion of DAAM resulted in an increase in the emulsion’s stability and film’s solvent resistance; The DSC test demonstrated that boosting the crosslinking degree was advantageous in improving the T g of the film; according to FT-IR and microscopic tests, the crosslinking reaction took place in the system. The self-crosslinking acrylic emulsion of this system has a certain application prospect as a binder.
