DLLA

Racemic lactide can be used to obtain racemic polylactic acid through homopolymerization, or it can be polymerize by ring-opening copolymerization with other cyclic monomers to produce random or block copolymers. In particular, the copolymerization of lactide with glycolide to form PLGA plays an important role in drug controlled release and surgical sutures.

■ This series of products is made from biodegradable materials. During storage, it should be kept away from water, acidic substances, alkaline substances, alcohol-based reagents, and other agents that may cause degradation.

■ The products should be stored in a sealed, dry, and low-temperature environment (frozen at -20 degrees Celsius in a refrigerator). Use a sealing machine for packaging (remaining unused products should not be stored in self-sealing bags).
