Rubber properties are modified byaddition of chemical substances and ingredients causing physical and chemical modifications. Theingredients modify rubber hardness， durability and impact strength； increase its resistance to wearing， oils，oxygen， solvents， heat， and cracking， which makes rubber more suitable for the use in various applicationareas. The infrared spectroscopy methods provide identification of rubber and other polymers and their mixturesbasing on examination of spectra of the polymers and their pyrolysis products and films cast from solutions，as every type of rubber has its unique spectral properties. The obtained spectral data may be used for a variety of applications， including identifying unlabeled material，process control， raw material acceptance， etc. EQUIPMENT AND REAGENTS USED FOR ANALYSIS The following equipment and reagents are used for the analysis： Fourier-Transform IR spectrometer InfraLUM FT-08 (with software)； . Cell or ATR accessory； Personal computer. ADVANTAGES OF InfraLUM@ FT-08 SPECTROMETERS Easy to operate High selectivity . Spectrum scanning takes just one minute No sample pretreatment needed A wide range of accessories may be used for analysis MEASUREMENTMETHOD In accordance with the method procedure， the sample is prepared from an extracted and dried rubber eitheras a pyrolysis product or a film deposited from solution by evaporation. The sample deposited on a salt substrate is placed into a cell， and then infrared spectrum is recorded atwavelengths from 2.5 to 15 pm (4000-667 cm) at 4 cm"resolution and scanning time of 60 s.
