ABSTRACT:
The subject invention provides a method and apparatus for the control and or rectification of molecular weight distribution of polymeric quenchants. In general this is accomplished by selective filtration and elimination of lower molecular weight constituents and the resulting restoration of the molecular weight balance which is necessary to maintain the quench of the desired severity.
