Polymers and Their Monomers

Polymer - Monomers


Homopolymers (Only one monomer)

Cellulose – Glucose
Natural rubber – Isoprene (2-metyl-1, 3-butadiene)

Neoprene - Chloroprene
Nylon-6 - caprolactum

Polyacrylonytrile (PAN) or Orlon – Vinyl cyanide (acrylonitrile)
Polyethelene - Ethylene (Ethene)
(Popularly polythene)
Polyethyl acrylate (PEA) - ethyl acrylate
Polymethyl methacrylate (PMMA) – Methyl methacrylate
Polymonochlorotrifluoroethylene (PCTFE) - chlorotri-fluoroehtylene
Polypropylene – Propylene
Polystyrene or Styron – styrene
Polytetrafluoroethylene (Teflon or PTFE) - tetrafluoroethylene
Polyvinyl chloride – Vinyl chloride
Proteins - Alpha-Amino acids

Starch - Glucose


Copolymers (Two different monomers)

Bakelyte (Phenol formaldehyde resin) - Phenol and Formaldehyde
Buna-S - 1,3-butadiene and styrene
Dacron (Polyster) - Terephthalic acid and ethylene glycol
Glyptal - ethylene glycol and phthalic acid
Melamine polymer (Melamine formaldehyde) - Melamine and fromaldyhyde
Nylon-66 - Hexamethylenediamine and adipic acid
Saran - vinyl choride and vinylidene chloride
