  • Are unsaturated polyester resins bio-based?
  • Herein, the successful design of a highly bio-based family of unsaturated polyester resins (UPRs) is presented, comprising of an isosorbide (ISO) incorporated unsaturated polyester prepolymer (UP) and a reactive diluent of 4-vinylguaiacol acetyl ester (ACVG).
  • How to synthesise unsaturated polyester resins from pet glycolysed products?
  • In recent years, there have been several attempts to synthesise unsaturated polyester resins (UPR) from PET glycolysed products [ 1, 5, 11 – 15 ]. In general, the process involves the polyesterification of glycolysed PET with unsaturated diacids and the crosslinking of the obtained polyester with styrene monomers.
  • Can DCPD-modified unsaturated polyester resins be cured?
  • The study of the curing reaction of DCPD-modified unsaturated polyester resins was conducted by several Taiwanese authors [ 10 ]. In this study polyester (based on MA, DEG and DCPD) was prepared in the classic way - without the addition of water.
  • Can recycled polyethylene terephthalate be used to make unsaturated polyester resins?
  • A method for the preparation of unsaturated polyester resins based on recycled polyethylene terephthalate has been studied.
  • Does molecular weight affect the properties of unsaturated polyester resin?
  • Samples UPR-4 and UPR-6 formed physical gels when dissolved in styrene, with UPR-4 remaining in gel form even when excess styrene was added. Since UPR-4 and UPR-5 have the same composition of monomer mixtures, it can be concluded that the molecular weight has a significant effect on the properties of the unsaturated polyester resin.
  • What are DCPD based unsaturated polyesters?
  • DCPD-based unsaturated polyesters are usually reaction products of glycols, maleic anhydride (MA) and DCPD. Specialities including vinyl esters based on DCPD are commercially available as well [ 6 ]. There are several procedures for the preparation of DCPD polyesters resins.
