Synthesis and Application of a Low Emulsifier Content Composite Polyacrylic Latex for Leather Finishing

WOS: 000444153900004A composite polyacrylic latex via two stage seeded emulsion polymerization with low emulsifier content (0.5 wt.%) was synthesized and characterized by means of particle size and zeta potential analysis, FTIR and differential scanning calorimetry (DSC). The results verified a very uniform particle size distribution and good electrostatic stability. The different phases of the composite polymer were evidenced by DSC analysis with two clear phase transitions. The application of the latex on leathers as coating binder revealed good fastness levels to dry/wet rubbing and water spotting. The synthesized composite latex was found to be good candidate for producing cost-effective waterborne binders with good performance
