Abstract: it is mentioned that the fraction of 130-190°С liquid products of the pyrolysis of low-octane petrol and para-arylalkylphenol which is obtained by the catalytic arylalkylation of phenols are reacted with acetic acid and benzoyl chloride to obtain aceto- and benzophenone which are used as photo stabilizer in polystyrene. The process has been accomplished by using batch and continuous devices. The desired product was separated by the rectification of obtained alkylate. The physical and chemical properties of para-arylalkylphenol have been determined as Tb.=160-180°С (at 10 mmHg.); n_D^20 1.5730, ρ_4^40 0.9825; molecular weight 200 Aceto- and bezophenones were tested as photo-stabilizer in polystyrene. In contrast to the known stabilizers when aceto – and benzophenones as proposed after the tests results were added into styrene, it was determined that optical constant density of polystyrene samples was constant after photo-irradiation at 8 hours.
