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.

PDLLA is approved by the FDA as an auxiliary material and internal fixation device for corrosion inhibitors and injection microcapsules, microspheres and implants, it is also used as a porous foam scaffold for tissue engineering cell culture, bone fixation or tissue Tissue engineering of repair materials; surgical sutures, etc.

Frequently Asking Questions

1. What is the difference between PLLA and PDLLA?

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.
