Direct determination of vinyl acetate content of ethylene vinyl acetate copolymers in thick films by infrared spectroscopy. An infrared spectroscopic method was developed for the determination of vinyl acetate content in thick films of ethylene vinyl acetate copolymers. The a 3460 a 3610 ratio was used for the quantitative analysis. Acetic acid vinyl ester.

Attenuated total reflectance infrared atr ir spectrum of ethylene vinyl acetate copolymer with properties. The technique is simple quick and does not require a complicated sample preparation procedure. Raman spectra of ethylene vinyl acetate copolymers. This structure is also available as a 2d mol file or as a computed 3d sd file the 3d structure may be viewed using java or javascript.

Conclusion from the aforementioned examples it is evident that raman spectroscopy is a powerful technique for polymer analysis both in laboratory settings and on the process line. Infrared spectroscopy is used to determine the vinyl acetate incorporation into eva copolymers using the ratio between the characteristic band of acetoxy group and ethylene sequences.
