The research described in this paper was focused on development
of hybrid binders prepared via free radical polymerization
of acrylic monomers in a presence of an unsaturated alkyd resin
by emulsion polymerization technique. Hybrids with different
alkyd–acrylic ratios and acrylic parts were prepared and examined.
As a best, hybrids with solid content of 46% and monomer
conversion of 97% were prepared. The binders were characterized
according to their solid content, conversion, viscosity, pH and particle
size
temperature measurements, as well as via performance studies. The performance evaluation was
focused on investigation of drying, penetration and water repellency ability, as well as on film formation
and surface topography studies. The binders were compared to references of an alkyd emulsion, acrylic
latex and a blend made of them. The results showed that alkyd–acrylic hybrids with synergistic and
improved properties can be prepared.
