The bulk PUs obtained with the use of diol and triol have been studied by electron microscopy. The fracture surface morphology of these samples has been compared. It has been found that the degree of crosslinking can be responsible for different mechanisms of fracture and, thus, various fracture curves are observed. The solvent cast PUs (obtained with the use of diol) have been studied by polarized...
W Polsce na składowiskach zalega 1752,6 mln. Mg odpadów (stan na koniec 2005 roku). Z ogólnej ilości wytworzonych odpadów komunalnych w 2005 roku tj. 9354,3 tys.
