1 Instruction Division FIRST SEMESTER Course Handout (Part II) Date:23/07/2017 In addition to Part I (General Handout for all courses appended to the Time Table), this portion gives further specific details regarding the course. Course No : CHE G522 Course Title : Polymer Technology Instructor-in-Charge : Pradipta Chattopadhyay 1. Course Description: Classification of polymers; techniques; mechanism and kinetics of formation of polymers; different techniques for determination of different types of molecular weights; polymer structure; definition and measurement of glass transition and crystalline melting temperatures; polymer properties; viscoelasticity and rubber elasticity behavior; degradation and stability; polymer processing; rheology and applications. 2. Scope & Objective: Polymers are used extensively in a wide range of applications, from medical appliances, sporting and electrical goods to automotive, construction etc. Polymer engineers need to apply the traditional skills of chemical engineers, such as plant design, process design, thermodynamics, and transport phenomena, to various problems involving the production and use of polymers. This course is designed to learn the fundamentals of polymer technology from the basics of polymer chemistry, structure, synthesis and processing to more advanced topics, including structureproperty relationships, polymer mechanical properties, applications of polymeric materials, polymer rheology and processing. 3.
