“…Reacting the glycolysis polyol product with an alkylene oxide in a mol ratio of <1 mol of alkylene oxide per mol of active amine hydrogen atom in the glycolysis polyol product would yield a useful polyol [94]. It has been demonstrated that in the presence of MDI both of the split phases of the glycolysis mixture can be used as components of the urethane adhesive mixtures for bonding woods, metals, plastics, glass, ceramics, paper and leather [95]. In order to recycle the mixture of PUs and other plastics, the plastic waste is reacted with an alcohol mixture comprising at least one low-molecular-weight bi-functional alcohol and at least one polyether-polyol, and then the resultant glycolysis polyol is mechanically separated from the other plastic waste [96].…”
