Poly(D-Lactide) is another type of polylactide (PLA). PDLA is created through the polymerization of D-lactide. Poly(D-Lactic acid) and Poly(L-Lactide) have similar melt points and strengths.

Commercial polylactic acid is prepared by ring-opening polymerization of lactide. Lactide is made from lactic acid, and lactic acid can be derived from plant fermentation. Plant fermentation produces L-lactic acid, so the raw materials are very cheap, and the degradation of polylactic acid will produce lactic acid which is harmless to the human body, and D-lactic acid is harmful to the human body and is expensive. 


Poly(D-lactide) is a type of biodegradable polymer that is commonly used in various applications. It is often used in the medical field for sutures, implants, and drug delivery systems due to its biocompatibility and biodegradability.

Additionally, it can be used in packaging materials, 3D printing, and as a component in biodegradable plastics.

The solvent for Poly d-lactide is typically chloroform or dichloromethane. These solvents are effective in dissolving Poly d-lactide, allowing for easier manipulation and processing of the material.
