Özet
In this study, poly(vinyl acetate-co-butyl acrylate) latexes were synthesized by applying
semicontinuous emulsion polymerization method. Copolymerizations were carried out keeping constant
monomer ratio of vinyl acetate (VAc): butyl acrylate (BuA) as 85:15 at four different temperatures (55 ◦C, 60 ◦C,
65 ◦C and 70 ◦C) and constant stirring rate (350 rpm) with the using of N-methylol acrylamide as protective
colloid, ammonium persulfate potassium persulfate as thermal initiators, and 30 mole ethoxylated nonyl phenol
as nonionic emulsifier. The characterization of synthesized latexes were done by determining solid content,
conversion, Brookfield viscosity, particle size, the particle size distribution, surface tension and surface charges
of latexes.
