The course provides a complete overview of current and future aspects in polymer engineering. The finished polymer product properties are usually determined during the production process and hence it very essential to understand all the fundamentals and chemistry behind the polymerization process. Various terms such as reaction initiation, propagation, termination, reaction kinetics, thermal kinetics, molecular weight, and physical features such as microstructures, morphology, tensile and fractural strength etc. will be discussed in this course. The general polymerization concepts, principles, kinetics and methodology will be discussed through various examples. The course will be helpful for polymer and chemical engineer, students and industries for the advancement in the concepts related to polymer reaction engineering.INTENDED AUDIENCE :Chemical Engineering, Polymer Engineering, Polymer Technology, Mechanical EngineeringPREREQUISITES : NoneINDUSTRIES SUPPORT :Useful for all polymer industries and companies related to surface and interfacial technology such as plastic, paints, rubber, resin, adhesive, and advanced polymeric material industries.Reliance Industries Limited ;GAIL India Limited and many more
