| Abstract: | The use of naturally functionalized triglyceride oils in interpenetrating polymer networks (IPNs) is reviewed. An oil bearing
either hydroxyl or epoxide functionality may be crosslinked to form a soft elastomer in the presence of another monomer or
network to form an IPN, or in the presence of a linear polymer, to form a semi-IPN. Polymerization and characterization of
naturally functionalized triglyceride oils are mentioned, with emphasis on the distribution and effect of nontrifunctional
triglycerides on elastomer properties. The simultaneous synthesis of polystyrene/functional triglyceride oil IPNs is reviewed,
and several factors influencing IPN morphology and mechanical properties are discussed. The synthesis and properties of poly(ethylene
terephthalate)/functional triglyceride oil semi-IPNs are emphasized, with the importance of ester interchange in the synthetic
procedure, and factors influencing crystallinity and morphology are introduced. |
