Abstract
POSTUPAK ZA SINTEZU KOPOLIMERA MALEINSKE I AKRILNE KISELINE, cilj pronalaska je sinteza novog tipa kopolimera maleinske i akrilne kiseline koji sadrže 60 do 100% maleinatnih jedinica, odnosno 40 do 0% akrilatnih jedinica, obračunato na sumu obe jedinice u kopolimeru. Ovakvi kopolimeri pokazuju izrazite tehno-ekonomske prednosti u odnosu na ranije opisane kopolimere akrilne i maleinske kiseline. Prema optimizovanom postupku sinteze pomenutih kopolimera primenjuju se veoma koncentrovani alkalni rastvori maleinata (najbolje iznad 60%), vodonik peroksid i natrijumpersulfat kao katalizatori, i reakciona temperatura od 105 do 115В°C. Dobijeni kopolimeri imaju prosečne molekulske mase oko 20000 (dvadeset hiljada), a CCDC im iznosi u proseku oko 17 ml 0,25 M calcijum acetatapo 1 g kopolimera. Dobijeni kopolimeri pogodni su za primenu kao inhibitori inkrustacija, disperzanti i jonoizmenjivači.
