AB  - Two original art installations constructed from unsaturated polyester resins 
      (UPR) and four different reference UPR products (before and after UVB aging) were 
      analyzed by high-resolution 1D and 2D nuclear magnetic resonance (NMR) 
      spectroscopy. Breaking strain studies were also conducted for the four UPR model 
      products before and after different aging procedures (moisture, UVB exposure, 
      melt/freeze). NMR analysis of the chemical composition of the UPR resin extracts 
      showed they contain several low MW organic compounds and oligomers rich in polar 
      -OH groups that play a significant role in the degradation behavior of the 
      composite UPR materials. Statistical analysis of the NMR compositional data 
      showed that styrene and benzaldehyde contents can be used to differentiate 
      between fresh and aged UPR samples. The phthalate and propylene glycol unit 
      speciation (esterified, primary or secondary -OH) of the extracts provided 
      evidence that UPR resin C was used in the construction of the two art 
      installations, and direct comparison of (1)H and (13)C NMR spectra verified this 
      compositional similarity. UPR resin C was shown by both NMR and breaking strain 
      studies to be the reference UPR most susceptible to degradation by different 
      aging procedures, a characteristic attributed to the lower styrene content of 
      resin C.
