AB  - The general literature procedure for the preparation of the reversible addition-fragmentation chain transfer (RAFT) agent 2-(2-cyanopropyl)-dithiobenzoate (CPDB) was modified by omitting the recrystallisation of the intermediate di(thiobenzoyl)disulphide. The yield of the CPDB in the simplified synthesis was increased four times compared to the standard one. The behaviour of the CPDB obtained by the modified procedure and by the standard one in the polymerisation of methyl methacrylate was investigated. The CPDB synthesized by the simplified procedure showed itself to be a good RAFT agent, giving excellent control over the polymerisation of methyl methacrylate and it behaved in the same manner as the CPDB prepared by the literature method. The obtained poly(methyl methacrylate) had a narrow molecular weight distibution (PD = 1.1).
AB  - Standardni postupak sinteze 2-(2-cijanopropil)-ditiobenzoata (CPDB) agensa iz literature za RAFT polimerizaciju, odnosno za reverzibilnu adiciono-fragmentacionu transfer polimerizaciju, je modifikovan izostavljanjem prekristalizacije međuproizvoda bis-(tiobenzoil)disulfida. Prinos CPDB-a sintetisanog pojednostavljenim postupkom je četiri puta veći u odnosu na prinos CPDB-a sintetisanog standardnim postupkom. Ispitano je ponašanje CPDB-a dobijenog modifikovanim i onog dobijenog standardnim postupkom u polimerizaciji metil metakrilata. CPDB dobijen pojednostavljenim postupkom pokazao se kao dobar RAFT agens koji uspostavlja odličnu kontrolu polimerizacije metil metakrilata i koji se ponaša na isti način kao CPDB sintetisan standardnim postupkom. Dobijeni poli(metil metakrilat) ima usku širinu raspodele molskih masa (PD = 1.1).

AB  - The free radical copolymerisation of itaconic anhydride and methyl methacrylate in solution was studied at 60 °C. The copolymer composition was determined by 1H-NMR spectroscopy and the obtained monomer reactivity ratios were calculated, rITA = 1.35±0.11; rMMA = 0.22±0.22 (by the Fineman-Ross method) and rITA = 1.27±0.38; rMMA = 0.10±0.05 (by the Mayo-Lewis method). The synthesised copolymers were modified by reaction with di-n-butyl amine. The copolymer composition after amidation was determined by elemental analysis via the nitrogen content. Amidation of the anhydride units in the copolymers with di-n-butyl amine resulted in complete conversion to itaconamic acid.
AB  - Ispitivana je radikalna kopolimerizacija anhidrida itakonske kiseline i metil-metakrilata u rastvoru na 60 °C. Sastav kopolimera određen je 1H-NMR spektroskopijom i izračunati su odnosi reaktivnosti monomera, rITA = 1.35±0.11; rMMA = 0.22±0.22 (metodom Fajnman-Ros) i rITA = 1.27±0.38; rMMA = 0.10±0.05 (metodom Mejo-Luis). Sintetizovani kopolimeri su modifikovani reakcijom sa dibutil-aminom. Nakon amidacije sastav kopolimera određen je elementalnom analizom na osnovu sadržaja azota. Amidacijom anhidridnih jedinica u kopolimerima dibutil-aminom nastale su komonomerne jedinice itakonamične kiseline.
