Polymers Classification

What are Polymers?
1. Large Mollecules
2. Large Mollecular mass
3. Essential in...
  1. Plastics
  2. Elastomers
  3. Fibres and Paints
  4. Varnishes
4. Formed by polymerisation
Based on Source
1. Natural Polymers
  1. In plants & animals
  2. Ex. Protein, cellulose, starch
2. Semi-Synthetic Polymers
  1. Cellulose derivates
  2. Ex. Cellulose nitrate
3. Synthetic Polymers
  1. Man-madae
  2. Ex. Plastic
Based on Structure
1. Linear
  1. Long & straight chains
  2. Ex. Polyvinyl Chloride
2. Branched Chain
  1. ex. Low density polythene
  2. Linear with Branches
3. Cross Linked or Network
  1. Contain strong Covalent Bonds
  2. Ex. Bakelite, Melamine
Based on mode of Polymerisation
1. Addition polymers
  1. Homopolymers: One type of monomer
  2. Formed by adding monomers with double/triple bonds,
  3. Copolymer: Different types of monomers
2. Condensation Polymers
  1. Eliminates small mollecules
  2. The reaction between two different monomeric units
Based on Molecular Forces
1. Elastomers
  1. Elastic
  2. Weak Intermolecular forces
  3. ex. neoprene
2. Fibres
  1. Thread forming solids
  2. High tensile strenght
  3. Strong intermolecular forces
  4. ex. Nylon 6
3. Thermoplastic Polymers
  1. Almost no branched chains
  2. Heat=Softens Cool=Hardens
  3. Intermolecular attraction
4. Thermosetting Polymers
  1. Heavily branched molecules
  2. Cannot be reused
