Toughening of Polylactide (PLA) by in-situ reactive compatibilization with isosorbide containing copolyester |
| 초록 |
Blends with different ratio of polylactide (PLA) and poly (1,4-cyclohexane dimethylene isosorbide terephthalate) (PEICT) were prepared by melt processing. The two immisicible polymers were compatibilized by reactive blending using a multifunctional epoxy oligomer. Infrared spectroscopy and rheological analysis confirmed the formation of a copolymer of PLA and PEICT that reduces the interfacial tension in the PLA/PEICT blends. The improved interfacial adhesion formed a co-continuous phase morphology from a previously sea-island morphology, which is observed by SEM at the fractured surfaces. The added PEICT showed reinforcing effect on PLA by improving the impact strength. The reduced interfacial tension by the compatibilizers improved the energy transfer between the two polymers giving the blends even higher impact strength than the prisitne blends. |
