6. POLYMERS and elastomers Lecture no. 1 Objectives: Definition‚ Functionality‚ Classification of high polymers – based on origin‚ molecular structure. 6.1.1. DEFINITION: The word polymer is derived from the two greek words‚ poly and meros‚ meaning many and parts or units respectively. Polymers are macro molecules formed by linking smaller molecules repeatedly‚ called monomers. Examples: Polythene is formed by linking a large number of ethene (or ethylene) molecules together
