Novel DCPD-modified polyester containing epoxy groups: thermal, viscoelastic, and mechanical properties of their wood flour filled copolymers

摘要: In this article, the synthesis of novel DCPD-modified polyesters containing epoxy groups and their possible utilization as polar matrices for wood flour filled copolymers have been studied. The polyester was prepared during three-step process. First, addition reaction maleic acid to DCPD norbonenyl double bond has performed. Then, polyesterification acidic ester DCPD, cyclohex-4-ene dicarboxylic anhydride, ethylene glycol (ethane-1,2-diol, EG) or neopentyl (2,2-dimethyl-1,3-propanediol, NP) in presence catalyst carried out using melt condensation technique. Finally, oxidation process led obtain groups. structural characterization functionality FTIR HNMR spectroscopic methods. thermal, viscoelastic, mechanical properties unfilled studied by DSC, DMA, TGA analyses, three-point bending test, Brinell’s hardness. performed investigations indicated that can be successfully applied preparation due “compatibility” with hydrophilic surface which resulted stronger interactions between polymer thus producing were characterized improved thermo-mechanical compared copolymers.
