Abstract
POSTUPAK ZA DOBIJANJE CELULARNIH ILI MIKROCELULARNIH POLIURETANSKIH PENA, naznačen time, što obuhvata faze: - obrazovanje karboksi-modifikovanog poliola reakcijom karboksilne kiseline odabrane iz grupe koju sačinjavaju fumarna kiselina, maleinska kiselina, itakonska kiselina i njihjove smese, i poliola, u prisustvu inicijatora slobodnih radikala peroksi tipa, pri čemu je maseni odnos poliol karboksilna kiselina od oko 93:7 do oko 75:25, a reakciona temperatura od oko 25В°C do oko 150В°C; - reakciju poliizocijanata sa karboksi-modifikovanim poliolom, na temperaturi od oko 25В°C do oko 150В°C, radi obrazovanja poliuretana ili drugih proizvoda - derivata izocijanata i ugljen dioksida, pri čemu ugljen dioksid deluje kao in situ sredstvo za oblikovanje za penu pomenutog poliuretana, zajedno sa dopunskim sredstvom za oblikovanje odabranim iz grupe koju sačinjavaju hlorovani fluorougljovodonici, hidrogenovani hlorovani fluorougljovodonici, voda i njihove kombinacije, pretvarajući poliuretan u celularnu ili mikrocelularnu poliuretansku penu. Prijava sadrži još 1 zavisan zahtev.
