Polymer Chemistry is a subject in the Chemistry Programs, student have a natural curiosity about polymeric materials, that we use in our everyday activities. Our proposal is to apply cooperative learning in the Interfacial polymerization of Nylon 6,10 experimentation. The specific objectives of our project can be summarized as: To identify the origin of the raw materials used for industrial synthesis, to become acquainted with the most important processes used for the synthesis, To identify the most important variables related with the control of the polymerization process, To correlate the physical chemical properties with the final applications of this material. The reader will find in the text a series of questions that will make him reflect--so-called complementary activities-- promoting the development of competences complementary ones based on research exercises. Through to synthesize unsupported membranes of Nylon 6,10 by unstirred interfacial step polymerization of hexamethylene diamine (HMDA) and sebacoyl chloride. To observe the quality of the nylon film produced as a function of the rate of removal and of the concentrations of diamine and diacid chloride in their respective phases. The reader will find in the text a series of questions that will make him reflect--so-called complementary activities--promoting the development of competences complementary ones based on research exercise
