摘要：
Boltorn hyperbranched aliphatic polyesters were functionalised with polyhedral oligomeric silsesquioxane (POSS) and blended with thermoplastic polyurethane (TPU). Functionalisation was confirmed using FTIR. Incorporation of POSS-functonalised Boltorn enhanced thermal stability and mechanical strength. Creep decreased while permanent deformation increased with denrimer concentration. Blends exhibited an increase in storage modulus (E') and glass transition temperature (T-g).
