| Abstract: | Summary Thermal and dynamic mechanical properties of carbon dioxide and propylene oxide alternative copolymer, poly(propylene carbonate)
(PPC), and the end-capped PPC with maleic anhydride were investigated by means of TG and DMA. A master curve of the storage
modulus vs. frequency can be deduced from the isochronal curves. Physical parameters of both plain and MA end-capped PPC were discussed.
The results showed that for maleic anhydride (MA) end-capping PPC, an improvement of its thermal stability and mechanical
properties accompanied with some modifications of the viscoelastic behavior were obtained. |
