The composition of copolymers was determined by elemental analysis and atomic emission spectroscopy based on inductively coupled plasma (ICP-AES). We established the effect of the reaction conditions on the yields of syntheses. The average molar masses and polydispersities of the products were determined by size exclusion chromatography (SEC)Sulfonirane polianiline (SPAN) smo pripravili s kopolimerizacijo anilina in 3-aminobenzensulfonske kisline (metanilna kislina) v različnih reakcijskih razmerah. Pri sintezah smo spreminjali razmerja monomerov, količino oksidanta amonijevega persulfata, reakcijsko temperaturo in čas. Sestavo kopolimerov smo določili z elementno analizo in atomsko emisijsko spektroskopijo z induktivno sklopljeno plazmo (ICP-AES). Določili smo vpliv reakcijskih pogojev na izkorisstke sintez. Z izključitveno kromatografijo (SEC) smo pri produktih ugotovili povprečne molske mase in polidisperznostNadaljuje se kot: Materiali in tehnologijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
