If you use a suitable reaction catalyst, the polymerization of lactide is ring opening, through which to create the PLA. The resulting plastic has properties similar to those of polyolefins and polystyrene. It can be converted into various products, mainly from the field of packaging and optical fiber. After using the polymer by hydrolysis may be destroyed and transformed into lactic acid, and after that, through metabolism, breaks down into carbon dioxide and water snake. This process can be flexible enough in terms of standard industrial composting, but it should be noted that at lower temperatures, the process of destruction is very slow. PLA has been used successfully in a number of areas that have been traditionally occupied by polymer-based fuels. However, the use of PLA and materials related to the PLA, in a large scale in some way constrained. The two properties, to some extent restricting the PLA, – it is a relatively low glass transition temperature and low impact strength.
Moreover, the commercially used catalysts / initiators for the production of PLA, though useful, are used only slightly; new catalysts for the polymerization of lactide and other cyclic esters can significantly increase the degree of control over the polymerization process. In this task, the group payer examines progress in the synthesis of biocompatible (ie, non-toxic) initiator for the polymerization of lactide. The key parameters are the initiator of the polymerization rate, molecular weight control, and regulation stereobalansa. Other desirable properties include low cost, stability, prevalence, no color or odor in the finished product, as well as low toxicity.
