Detailed Description
Description: Specializes in medical bio-degradable polyester materials research and product development, has been synthesized poly-lactic acid, poly-lactic acid glycolic acid, poly anhydride, poly trimethylene carbonate, poly DIOXANONE and other materials, and these Materials developed electro-spinning film, biodegradable fibers, porous foam biodegradable stents and other medical products. .Aggregation and processing of all products were carried out one hundred thousand grade clean room, to medical grade standards, polymerization process is stable, polymer product after repeated fractionation (extraction) process, molecular weight distribution of ≤ 2.0, in order to ensure the stability of product and quality.
1.1, racemic polylactic acid (D, L-PLA) 1.2, L-polylactic acid (L-PLA) 2, poly-lactic acid / glycolic acid (PLGA) (LA / GA = 90/10, 80/20, 75/25, 60/40, 50/50) 3, poly-lactic acid gel - monomethyl polyethylene glycol / polylactic acid copolymer (MPEG-PLA, MPEG-PLGA) 4, polyethylene glycol / polylactic acid copolymer (PLA-PEG-PLA, PLGA-PEG-PLGA) 5, terminal carboxyl polylactic acid (PLA-COOH, PLGA-COOH) 6, poly anhydride (P (CPP-SA)) - poly [1,3 - bis (carboxy phenoxy) propane - Kwai acid] copolymer 7, poly trimethylene carbonate and its copolymers (TMC, P (LA-TMC)) 8, poly dioxo-cyclohexanone and its copolymer (PPDO, P (LA-PDO))
