| Popis: |
Termoplastic polyurethane on the polybutadienediol has been synthetized. To obtain good mechanical properties, the synthetized polymers should be at high molecular weight ?$(M_w \g10^5 g/mol)$?. To vary the molecular weight, the surplus isocyanate has been varied at given reaction conditions. Reaction kinetics and molecular weight have been determinated and measurements of viscosity have been carried out. Sintetizirali smo termoplastični poliuretan na osnovi polibutadiendiola. Za doseganje uporabnih lastnosti so potrebne dovolj visoke molske mase(?$M_w$? nad 100000 g/mol), zato smo pri danih reakcijskih pogojih spreminjali odstotek prebitnega izocianata. Določili smo kinetiko reakcije ter izmeili molske mase in viskoznosti. Nadaljuje se kot: Materiali in tehnologije |
