The influence of morphology on the (hydrolytic degradation of as-polymerized and hot-drawn poly (L-lactide))

The influence of morpho-logy on the hydrolytic degradation behavior of poly(L-lactide) has been studied. High molecular weight and highly crystalline as-polymerized poly(L-lactide) was obtained in high yields through melt polymerization. Poly(L-lactide) fiber with a draw ratio of 5.6 was obtained by hot-drawing solution-spun fiber.
