| Summary: | One group of polymers that may help relieve the dependence on crude oil is
based on itaconic acid, the biotechnological production of which has become
feasible. Itaconic acid and its derivatives can easily be incorporated into
polymers and may serve as a substitute for petrochemically derived acrylate
or methacrylate monomers. The applications of polymers based on itaconic
di-esters depend largely on their thermal stability. The thermal stability of
poly(di-itaconates) is dependent, not only on the general structure of the
monomer repeating unit, but also on the structure of the ester substituent.
Depolymerization, initiated by b-scission or random main chain scission, is
the dominant thermolysis mechanism in most cases. The depolymerization of
poly-(di-itaconates) may be accompanied by de-esterification, elimination,
cross-linking, random main or side chain scission and carbonization.
Comparison of the thermal degradation mechanism of polymeric di-esters of
itaconic acid to that of corresponding poly(methacrylates) confirms the
viability of substituting poly(methacrylates) by poly(di-itaconates).
