Preparation and Properties of Self-reinforced L-and D,L-lactide Copolymer Rods

Since highly crystalline poly (L-lactide) (PLLA) degrades rather slowly in a biological environment and the crystalline domains remaining after partial degradation of the implant material give rise to an inflammatory response of the surrounding tissue, L- and D,L-lactide copolymer[P(L-DL)LA] having a low crystallinity is preferred in surgical applications. The thermal transitions and the mechanical properties of P(L-DL)LA rods were discussed in this paper. It was found that the self-reinforced P(L-DL)LA[SR-P(L-DL)LA] was strong enough in terms of mechanical properties compared with the self-reinforced PLLA[SR-PLLA].
