Abstract

Process for the preparation of an additive that acts as a critical fluid reducing agent for hydrocarbon mixtures, comprising the hydrogenation of a copolymer of 1,3-butadiene and styrene with a weight ratio between the butadiene and styrene units of between 98/2 and 50/50, to obtain a hydrogenated copolymer with a molecular weight of between 1000 and 200,000, characterized by the fact that the copolymer used as the initial material has a content of vinyl unsaturation of between 42 and 8% in weight, respectively, based on the aforementioned field of relationship, and that the total olefinic unsaturation, after hydrogenation, is between 0.5 and 12% by weight, determined by infrared absorption spectroscopy, or by 3 to 15% by weight, determined by titration with iodine monochloride.
