A method for the fractionation of reclaimed polymer in at least one solvent in a process for purifying reclaimed polymers plastic recycling to increase their use in secondary applications. The reclaimed polymer is dissolved in a solvent within a reactor vessel having a stack of perforated discs which are oscillated....

A method to dissolve a polymer in a solvent in a process for the removal of additives in plastics, in which the polymer and solvent are combined in a reactor vessel having a stack of perforated discs which are oscillated. The linear motion of the stack speeds up dissolution time to minutes rather than hours and the ...

A method to purifying reclaimed polymers for improving the grade and consistency in the properties of mixed recycled plastic to increase their use in secondary applications. A desired property of the purified reclaimed polymer is determined with a first parameter value of a reclaimed polymer feedstock also determine...
