The use of plastics material whose waste don’t contaminate the environment, is looking for every time by Science and Technology development. This requirements are fulfill by polyhydroxyalkanoates (biodegradable thermoplastics), obtaining by microbiological method. These polyesters have properties similar to the polypropylene, used in containers. The very slow speed of crystallization is a problem in this material prosecution. In presently work, the kinetics of isothermal crystallization process of the poly (b-hydroxybutyrato) co-11% (b-hydroxyvalerato) and their adipato mixtures was studied by the Differential Scanning Calorimetric  technique (DSC).
