Excluded solvent
WebFor a dilute chain in a good solvent the chain experiences repulsive interactions between chain elements which lead to excluded volume and good solvent scaling. As the concentration is increased beyond the overlap concentration the repulsive interactions that lead to good solvent scaling are screened by the presence of other chains within the coil. WebThis rule allows for non-hazardous classification for rags or wipers used with common industrial solvents. The final rule summary provides the basics but Closed Loop …
