lower critical solution temperature 

 

Recommended acronym: LCST  
Critical temperature below which a mixture is miscible.  
 
Notes:  
1. Below the LCST and above the UCST, if it exists, a single phase 
exists for all compositions.  
2. The LCST depends upon pressure and the molar-mass distributions 
of the constituent polymer(s).  
3. For a mixture containing or consisting of polymeric components, 
these may be different polymers or species of different molar mass of 
the same polymer.
