Some good polymer databases:
[1] G. Beamson, D. Briggs, High Resolution XPS of Organic Polymers - The Scienta ESCA300 Database, Wiley Interscience, 1992
(Note: An excellent resource, every XPS lab should have a copy!)
[2] Kratos Polymer Handbook http://www.kratos.com/EApps/polybook2a.pdf
[3] B. Vincent Crist, Handbook of Monochromatic XPS Spectra, Polymers and Polymers Damaged by X-rays, Wiley, 2000
