| Propanoic acid, 2-hydroxy-, homopolymer Usage And Synthesis |
| Uses | polylactic acid (PLA) is a lactic acid polymer that can be used as a filler. | | Uses | Polylactic acid(PLA) was introduced in 1966 for degradable surgical implants. Hydrolysis yields lactic acid, a normal intermediate of carbohydrate metabolism. Polyglycolic acid sutures have a predictable degradation rate which coincides with the healing sequence of natural tissues. Polylactic acid, also known as polylactide, is prepared from the cyclic diester of lactic acid (lactide) by ring-opening addition polymerization. Pure DL-lactide displays greater bioresorbability, whereas pure poly-Llactide is more hydrolytically resistant. The actual time required for poly-L-lactide implants to be completely absorbed is relatively long, and depends on polymer purity, processing conditions, implant site, and physical dimensions of the implant. | | Uses | Poly(L-lactide); PLLA; is a semi-crystalline biodegradable polymer used in drug delivery; the acetylene functionality is commonly utilized in copper mediated ligation. PLLA is soluble in toluene; THF; CHCl3; and CH2Cl2; insoluble in methanol; hexane and ether. | | Definition | ChEBI: A macromolecule composed of repeating 2-hydroxypropanoyl units. | | General Description | CarbonX?
