Redox Optimization for Emulsion Polymer Post Reaction

Reduction of free monomer content is required in the manufacture of emulsion polymers to lower VOC emissions. This has become more critical as consumers are demanding formulations with reduced odor.

Conventional post polymerization techniques using redox pairs can achieve low levels of residual monomers, but this can increase production time, add cost, and reduce production capacity.

A post-polymerization redox optimization study was conducted on a production latex made with a persulfate to thermally initiate the main polymerization. Various redox combinations were tested in the post-polymerization stage at different dosage levels and feed rates to minimize redox quantity, residual monomers, and time. 

This webinar will show with a redox optimization study that the mentioned hurdles can be overcome and excellent results are within reach.
