Ethylene Vinyl Acetate Infrared Spectrum

Attenuated total reflectance infrared atr ir spectrum of ethylene vinyl acetate copolymer with properties.

Ethylene vinyl acetate infrared spectrum.

Spectral changes in the raman spectra of eva with increasing lamination time which equals increasing degree of cross linking were mainly detected in the ch vibrational regions namely in. The a 3460 a 3610 ratio was used for the quantitative analysis. The technique is simple quick and does not require a complicated sample preparation procedure.

5 nmr 6 ftir and 2 raman. 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. Acetic acid vinyl ester. An infrared spectroscopic method was developed for the determination of vinyl acetate content in thick films of ethylene vinyl acetate copolymers.

Direct determination of vinyl acetate content of ethylene vinyl acetate copolymers in thick films by infrared spectroscopy. Vibrational spectroscopy was found to be a suitable method for the determination of the degree of cross linking of ethylene vinyl acetate eva polymers. Compound ethylene vinyl acetate copolymer with free spectra. 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.

Polymer testing 1999 18 7 551 557. Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. 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.
