Despite the fact that natural polyesters were first observed over 160 years ago
and first applied in the form of synthetic glyceryl phthalate used as impregnating
materials and coatings during World War I, the chemistry of polyesters developed
much later as a result of extended studies by Kienle and Carothers in which the
fundamental theory of polycondensation processes was established [1].
Polymers were synthesized from functional monomers as maleic anhydride and
glycols in the ...

Moreover, ricinoleic acid was modified with succinic or maleic anhydride to
produce nonlinear diacids. In all the above-mentioned cases, increasing the fatty
acid content ... Langer and coworkers have developed a trimellitic anhydride and
pyromellitic-based diacids to improve the mechanical properties of
polyanhydrides for tissue engineering applications, as well as comonomers for
antigen release [33-40]. The diacids were synthesized by refluxing either
trimellitic anhydride or ...

Varnishes made with ester gum and drying oils have good pigment wetting
properties and find applications in letterpress and lithographic inks. Its low acidity
means that it can be used in conjunction with metallic pigments. Its poor solvent
release limits its use in liquid inks and other evaporation drying systems. It is
prepared by heating rosin in a stainless steel kettle to approximately 260°C, then
slowly adding glycerol. The paleness of colour is preserved by the stainless steel
reaction ...
