Good Solvent

• No equations are planned.
  
  
• [Hiementz-60] describes a "good solvent" as a solvent which increases the coil dimensions.
  
  
• Lowering the temperature reduces the "goodness" of a solvent.
  
  
• Changes in the coil dimension effect viscosity
  
  
• Coil dimension also relates to the Mark-Houwink equation where the two extremes are:
  
  
  1. the sphere model
     
  2. the rigid rod model
     
     
• [Hiementz-60]The Flory Temperature is described as the temperature at which the "poorness" of the solvent exactly compensates for the excluded volume effect.
