dc.description.abstractThe 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).en
dc.description.abstractStandardni 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).sr
