Abstract

Acrylic-styrene latexes are being used in various industries such as textiles, rubber,
plastics, adhesives and coatings due to unique properties such as good durability,
compatibility with other materials, adhesion and ability to form continuous film, high
resistance to ultra violet, oxygen, water and solvents. In this paper, the most effective
factors on optimization of acrylic-styrene latexes' synthesis are studied namely: the type
and concentration of monomer, initiator and emulsifier, and temperature of polymerization
reaction. Optimized stable latex with the desirable performance may be achieved through
the following conditions: using butyl acrylate monomer as an optimum acrylate monomer
in combination with styrene hard monomer in the weight ratio 1-1.35, respectively; adding
functional monomers like α-methacrylic and acrylic acid of about 2 wt% relative to the
total weight of monomers, improving the film forming process via imparting cross-linking
cites into the acrylic chains; utilizing anionic emulsifier alone (like DSB and SDS) or in
combination with nonionic ones (like OP-10 and TX100) of about 0.5 wt% to 3 wt% of
the monomers; and using radical initiators like persulfates of potassium and ammonium
of about 0.25-0.5 wt% relative to the total monomers' weights. The reaction optimum
temperature range is determined to be approximately 75-80 °C. Adding fillers such as
rosin and silica nanoparticles into the acrylic-styrene matrix as much as 4 and 5 wt%,
respectively, results in improved water resistance of their films.
