Let’s Get Started


Chain Configuration

  • Polymer chains have three basic properties

    • The Molecular Weight,

    • The conformation of the chain in the space,

    • The configuration of the chain (microstructures),


Examples of Configurations and Conformations

  • Head to tail and head to head configuration

  • Trans-Gauche Conformation


Chemical Methods of Determining Microstructures


Physical Methods of Determining Polymer Chain Microstructure


Chiral Center

isotactic

syndiotactic

atactic

Stereo Chemistry of Repeating Units

  • Chiral Centers

  • Tacticity in Polymers

  • Optical Isomerism

  • Geometric Isomerism

  • Substitutional Isomerism


Meso And Racemic


Common Types of Copolymers

  • Unspecified Copolymers

  • Statistical Copolymers

  • Random Copolymers

  • Alternating Copolymers
