Özet
In this study, as a continuation of our previous studies on the chemical modification of different molecular weight polystyrenes (PS) with polyfunctionalized modifiers by using cationic catalyst, industrial waste oligostyrenes (IWOS) were used as raw material. These oligostyrenes are formed as waste material in the rectification of styrene, used for the production of PS in industry, and they cause environmental pollution. Chemical modification of these waste oligomers (IWOS) without waste residence was carried out with polyfunctional modifiers such as maleic (MA) and acetic anhydrides (AA) by using (BF3O)-O-.(C2H5)(2) catalyst in a single stage. Upon modification, it was determined that a maximum amount of functional groups (-COOH group 130 mg KOH/g polymer and 18 mol% CH3CO-group) was bonded to the structure of the oligostyrenes. Adhesion properties, corrosion resistance and impact of the polymeric coatings on metal surface changed as a result of the amount and structure of the polyfunctional groups bound to the polymer structure. It was determined that the modified IWOS had higher adhesion properties; and it was more resistant to corrosion and impact. Therefore, more economical resistant polymeric coatings were obtained; and their application areas were located by using this waste as raw material in polymeric reactions. (c) 2005 Elsevier B.V.
