Abstract
Inventia se refera la un procedeu de conditionare a poliolilor, în care, în scopul îmbunatatirii proprietatii de curgere libera a poliolilor ce sunt în conditii normale, cristalini, se adauga la polioli amine tertiale care contin cel putin 2 substituenti organici identici, avînd 2....12 atomi de carbon, în concentratie de 0,02 pîna la 0,15% în greutate amina, raportata la poliol, apoi se supune distilarii pentru purificare, în mod cunoscut.
