Abstract
naznačen time, što su unutrašnji zidovi reaktora za polimerizaciju, od metala ili zastakljeni, što se svi delovi koji mogu da dodju u dodir sa polimerizacionom sredinom, kvase, pre započinjanja reakcije polimerizacije, rastvorom ili disperzijom organske soli kod koje su: anjonski deo izvodi od mono- ili polikarboksi kiseline opšte formule: R1-/COOH/n, u kojoj je R1 alkil radikal, koji sadrži od 2 do 20 atoma C, ili aril ili prosti ili polikondenzovani aril ili alkilaril radikal, koji sadrži od 6 do 50 atoma C, a n je ceo broj koji se nalazi u opsegu od 1 do 4, ili od sulfonske kiseline, koja ima opštu formulu: R1-/SO3H/m, u kojoj R1 ima isto značenje kao gore, a n je ceo broj, koji se nalazi unutar opsega od 1 do 3; a katjonski deo se izvodi od organskih supstanci koje sadrže azot kao što su N-, NH i/ili -NH2 grupe. Prijava sadrži još 5 patentnih zahteva.characterized by the fact that the inner walls of the polymerization reactor are made of metal or glazed, that all parts that can come into contact with the polymerization medium are wetted, before starting the polymerization reaction, with a solution or dispersion of an organic salt in which: the anionic part is derived from mono- or polycarboxylic acids of the general formula: R1-/COOH/n, in which R1 is an alkyl radical, containing from 2 to 20 C atoms, or an aryl or simple or polycondensed aryl or alkylaryl radical, containing from 6 to 50 C atoms , and n is an integer ranging from 1 to 4, or from a sulfonic acid, having the general formula: R1-/SO3H/m, where R1 has the same meaning as above, and n is an integer, located within range from 1 to 3; and the cationic part is derived from organic substances containing nitrogen such as N-, NH and/or -NH2 groups. The application contains 5 more patent claims.
