PLA is actually a polymer of lactic acid, but the dimeric lactide is used as the precursor to avoid the water that would be formed in a direct poly-esterification. Monosubstituted monomers, on the other hand, may join together in two organized ways, described in the following diagram, or in a third random manner. Consequently, crystallinity is high and the cellulose molecules do not move or slip relative to each other. 5 x 10 4 M solution, the…. The high concentration of hydroxyl groups also accounts for the facile absorption of water that is characteristic of cotton.

Another group of polymers, characterized by a high degree of cross-linking, resist deformation and solution once their final morphology is achieved. Depending upon the microorganism, many of which are genetically engineered for this purpose, and the cultivation conditions, homo- or copolyesters with different hydroxyalkanic acids may be generated.
