Abstract

Kinetics of radical polymerizations of waterborne alkyd/acrylic hybrid resin via batch mini-emulsion technique was studied using REDOX INITIATORS (TBHP/Fe2+/EDTA/AsAc and TBHP/Fe2+/EDTA/SFS) at relatively low temperatures and THERMAL INITIATORS (BPO, KPS and AIBN) at higher temperatures to seek the most suitable initiator system. At the end of all reactions the unreacted monomer content was reduced using post-polymerization technique, consequently, leading to increased monomer conversion and film formation with improved properties. The KINETICs of mini-emulsion polymerization showed that in all redox initiator systems (Fe2+catalyst+EDTA chelating agent), the radials are produced at relatively low temperature with more efficient control of the reactor temperature. It was found that at 45oC TBHP/Fe2+/EDTA/SFS redox initiator system leads to 98% monomer conversion, a much higher rate than that of systems involved THERMAL INITIATORS.
