Influence of Water-soluble Azo Initiators on Cationic Latex particles

Batch cationic emulsion polymerization was carried out with styrene(St)and butyl acrylate(BA)as non-ionic monomer,Cetyl trimethyl ammonium chloride(CTAC)as emulsifier,and Azobis isobutyl amidine hydrochloride(AIBA)or Azo diisopropyl imidazoline hydrochloride(AIBI)as initiator.The effects of amount and molecule structure of initiators on latex particle size,PDI and particle morphology were analyzed.Results showed that higher initiator amount resulted in smaller particle size and higher PDI.Besides,smaller particle size were obtained when AIBI was used as initiator.
