Biodegradable Property ofPoly(latic acid) Film with Star-shaped Structure |
| 초록 |
Star-shaped Poly(lactic acid)(PLA) was synthesized by condensation polymerization reaction of latic acid and polyol. In order to observe biodegradable property of Poly(lactic acid)(PLA), we prepared Poly(lactic acid)(PLA) film and measured enzymatic degradable test using proteinase K enzyme at 37℃ for a week. The molecular weight of Poly(lactic acid)(PLA) was represented 6-PLA, 4-PLA, 3-PLA and linear PLA in high molecular weight order. The 4-PLA was showed high rate of biodegradation among them. This result indicates that the average molecular weight of chain influence the rate of biodegradation. |
