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 ...

We will review applications of the HMP in greater detail in subsequent
subsections. 2.2. Poly ( sodium maleate-a/r-alkyl vinyl ether)s Hydrocarbon-
soluble monomers such as maleic anhydride, alkyl vinyl ethers, and styrene can
be copolymerized by conventional free-radical polymerization, which, if followed
by anhydride hydrolysis to the dicarboxylic acid, results in an HMP. Additionally,
the copolymers can be modified with hydrophobes such as n-octy lamide as well
as fluorescent ...
