Abstract
POSTUPAK ZA DOBIVANJE MIKROĆELIJSKIH POLIURETANSKIH POLIMERA I MIKROĆELIJSKI POLIURETANSKI POLIMERI DOBIVENI OVIM POSTUPKOM. Pronalazak se odnosi na mikroćelijski poliuretanski polimer i postupak za njegovo dobivanje. Postupak obuhvata kontaktiranje u prisustvu sredstva za bubrenje pod reakcionim uslovima poliizocijanatnog preparata koji obuhvata bar 70 mas.% izocijanat terminalnog prepolimera koji ima izocijanatni sadržaj 14-28 mas.% dobiven reakcijom poliizocijanata koji sadrži bar 70 mas.% 4,4'-metilen difenilizocijanata sa poli(oksitetrametilen) glikolom koji ima prosečni hidroksilni ekvivalenat (250-15) sa preparatom koji sadrži aktivni vodonik i obuhata 70-90 masenih delova polietar poliola sa prosečnom hidroksilnom ekvivalentnom masom 500-5000, prosečnom molarnom funkcionalnošću 1,6-3,0 i primarnim hidroksilnim sadržajem bar 50% njegovog ukupnog hidroksilnog sadržaja i 1-30 masenih delova sredstva za prostiranje lanca koje ima ekvivalentnu masu manju ili jednaku 150. Količina prisutnog sredstva za prostiranje lanca u ovim uslovima obezbedjuje dobivanje polimera gustine 100-1000 kg/m3 a količina poliizocijanatnog preparata obezbedjuje 0,85 do 1,3 poliizocijanatnih grupa na aktivni atom vodonika preparata i prisutne vode.
