Description

Segmented SPUs were synthesized using 1,6 diisocianate hexane (HDI), 1,4 butanediol (BDO) as chain extender and poly(ethylene glycol) (PEG), poly(l-lactide) (PLLA) and poly (trimethylene carbonate) (PTMC) as macrodiols. These SPUs properties were studied by RMN 1H, GPC, DSC, DMA and Stress-Strain test, aiming to study variations with composition. Crystallization kinetics and morphology were also studied by POM and AFM. (author)
