METHOD AND SYSTEM FOR RECYCLING POLYVINYLIDENE CHLORIDE CONTAINING COMPOSITE MATERIAL

A method of recycling a composite material of polyolefin and polyvinylidene chloride. The composite material is subjected to a polar aprotic solvent to dissolve the polyvinylidene chloride from the composite material into the solution of the polar aprotic solvent. The undissolved composite material...

Beschreibung
Zusammenfassung:	A method of recycling a composite material of polyolefin and polyvinylidene chloride. The composite material is subjected to a polar aprotic solvent to dissolve the polyvinylidene chloride from the composite material into the solution of the polar aprotic solvent. The undissolved composite material from the solution can be collected and rinsed. The collected undissolved composite material being substantially free from polyvinylidene chloride. The polyvinylidene chloride can be precipitated out of the solution. The precipitated polyvinylidene chloride being substantially pure polyvinylidene chloride.
