Emulsification of vegetable oil-based resins was a daunting task
when the author began his research, but the subsequent technology
spawned a generation of stable emulsions for waterborne coatings
based on vegetable oil-based alkyd resins, oils and fatty acids.
Autoxidative polymerization of emulsified alkyd resins is an
innovative and original contribution to emulsion technology,
because conventional emulsion-polymerization is not applicable to
alkyd resins. Emulsified alkyd particles are polymerized while
dispersed in stable aqueous media-an original and patented
innovation. Smooth and fa- drying alkyd coatings are generated from
non-polymerized emulsions and air-dried with conventional metal
driers, and have met with marketing success. The pre-polymerization
innovation for emulsified alkyd particles provides very fast
air-drying coatings that have potential markets for interior
architectural latex coatings and waterborne pressure-sensitive
adhesives and inks. The author demonstrates his knowledge of
chemical reaction kinetics by employing a combination of oxygen
concentration, internal reactor pressure and other reactor
variables to finely control the rate and degree of autoxidative
polymerization. He meticulously calculates surfactant chemistry by
measuring hydrophile-lipophile balance values, and solubility
parameters to emulsify characterized resins. The relationship
between hydrophi- lipophile values and solubility parameters is
shown in explicit equations. Homogenization equipment used during
the course of this research to generate emulsions is shown in
detailed drawings together with concise particle size and
distribution data. The author reports research spawned
internationally by his research in the fields of alkyd-acrylic
hybrids, polyester and oil-modified urethane resins.
