ABSTRACT:The excellent chemical properties and resistance to oil of poly(acrylonitrile-co-butadiene), or nitrilebutadiene rubber (NBR), has led to the extensive use of these elastomers as O-ring material in the oil extraction industry. The degradation of NBR gaskets is known to occur during the well completion and oil extraction process when they are exposed to bromide fluids such as ZnBr 2 -based completion fluid. Samples of NBR, polyacrylonitrile, and polybutadiene were exposed to ZnBr 2 -based completion fluid and analyzed by attenuated total reflectance (ATR) and diffuse reflectance IR. These analyses showed that the ZnBr 2 completion fluid promoted the hydrolysis of the nitrile group to form amides and carboxylic groups. The carbon-carbon double bonds in NBR were unaffected after short exposure to ZnBr 2 -based completion fluid but were quickly hydrated in acidic bromide mixtures.

The practical application of high impact polystyrene (HIPS) depends on the resistance to aging in aggressive environments. The investigation of morphological, mechanical, and chemical properties was made on HIPS samples of various thickness. The property deterioration of HIPS caused by concentrated nitric acid and heat was studied. The diffusion through micropores formed visible cracks that finally led to the complete destruction into a powder. The rapid loss in mechanical properties was explained in terms of scission reaction of the graft polybutadiene (PB) with the homopolystyrene (PS) matrix. Comparative measurements of pure PS and PB under the same conditions were helpful in resolving parallel reactions that preferentially take place in PS and/or in PB sequences. It was established that higher degree of nitration caused by higher temperature results in increased insolubility owing to parallel crosslinking reactions. The nitric acid attack on HIPS caused scission reactions, which also led to the oxidative degradation, more pronounced in the PS phase in the soluble part of HIPS.
