Course Objective

The primary objective of this course is to make the student familiar with

the significance of Polymers as alternates of metals and alloys, study of their synthesis, characteristics, fabrication, and applications.

Course Outcomes

At the end of this course, the student will be able to

• Understand the significance of polymers
• Justify the substitution of metals and alloys with polymers
• Design the process of polymerization for a particular polymer
• Suggest a fabrication process for a particular polymer in accordance with the end application
