Poly(DL-lactide), or PDLLA, is a copolymer of dl-lactide that can be used for various medical applications, such as bioresorbable sutures, drug delivery systems, and tissue engineering scaffolds. It can degrade in the body by hydrolysis, producing harmless by-products that are metabolized or excreted.

Poly(DL-lactide) is not only versatile, but also customizable. You can choose the molecular weight and end group of your polymer to control its properties, such as crystallinity, mechanical strength, degradation rate, and drug release profile. Whether you need a low molecular weight polymer with free carboxylic acid end groups for fast degradation and drug release, or a high molecular weight polymer with ester end groups for slow degradation and drug delivery, we have it all!

Poly(DL-lactide) is also easy to use and cost-effective. It can be dissolved in various organic solvents, such as methylene chloride, tetrahydrofuran, ethyl acetate, acetone, chloroform, and hexafluoroisopropanol. It can also be processed by different methods, such as solvent casting, spray drying, emulsion, extrusion, and injection molding.

FAQs

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-PLA 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.
