Glikoliza odpadów poliuretanowych. Cz. II. Oczyszczanie oraz wykorzystanie glikolizatów

摘要: On the basis of literature review methods purification products polyurethane (PUR) waste glycolysis, with aim to reuse them in PUR syntheses, were presented. These are: extraction, distillation, and removing amine groups, detrimental further process preparation, by use e.g. alkylene oxides, glycidol ethers or cyclic carbonates. Methods testing glycolysis decomposition allowing finding optimal conditions described. Possibilities purified syntheses foams, elastomers adhesives as well biodegradable composites discussed.
