Poly(DL-Lactide) is a non-crystalline polymer, the appearance is white to light yellowish-brown irregular particles or powder. According to the end group of the tail, poly-DL-lactic acid is divided into three structural forms: hydroxyl-terminated, carboxyl-terminated and ester-terminated.

Poly(dl-lactide) is formed by the polymerization of DL-lactide. The product made of racemic polylactic acid has good biocompatibility and is used as a drug release carrier, the drug is embedded in a polymer which forms microspheres or microparticles.


Poly(DL-lactide) is primarily used in the medical field for various applications such as bioresorbable sutures, drug delivery systems, and tissue engineering scaffolds. It is a biodegradable polymer that can be easily metabolized in the body, making it ideal for these medical purposes.

The solvent commonly used for Poly DL-lactide is chloroform.

They have the same chemical molecular formula. Due to the different optical rotation of the structure, polylactic acid is divided into 3 types, L-polylactic acid, racemic polylactic acid, and D-polylactic acid. 

L-PLLA is a crystalline polymer with a glass transition temperature of 60 About 175 degrees, melting point is about 175 degrees, opaque. Poly (DL-Lactide) PDLLA is an amorphous polymer with a glass transition temperature of about 55 degrees, no melting point, and transparency.
