| Description |
The free radical copolymerization of di-n-docosyl
fumarate with vinyl acetate and n-alkyl (meth)acrylates was
carried out in toluene at 70°C using benzoyl peroxide as an
initiator. 1H NMR and carbon analysis was used to
determine the copolymer compositions. Monomer reactivity
ratios for high conversion polymerization were calculated by
Fineman-Ross, Kelen-Tüdös and conversion extension
Kelen-Tüdös methods. Gel permeation chromatography
was used to determine the molecular weights and polydispersity
indexes. In order to determine the stability of
polymers against thermal degradation, the kinetics and
mechanism of the thermal degradation of copolymers were
investigated by differential scanning calorimetry and thermogravimetric
analysis techniques. The energy of activation
of the degradation process was determined by several
thermogravimetric analysis models.
