In the early 1990s, at Newtown Square in Pennsylvania, Lyondell Chemical Company developed an interesting alternative to produce unsaturated polyesters. Based on this development, it became possible to produce a series of very flexible UPRs without sacrificing either mechanical or thermal properties. These products also showed good corrosion resistance when compared to conventional UPR resins. 

Since this is a new technology, a few short paragraphs to briefly explain the synthetic procedures of this process are in order. The synthesis details can also be found in the patent literature listed at the end of this article. 

All polyols were Lyondell Chemical s ARCOL products. Maleic anhydride and phthalic anhydride are commercially available, while all catalysts were also obtained commercially.
