| description | This study examines the restoration of waste plastic polymers based on LDPE,
HDPE or PP through dissolution/reprecipitation. Experimental conditions of
the recycling process, including type of solvent/non-solvent, original
polymer concentration and dissolution temperature were optimized. Results
revealed that by using the different prepared solvents/non-solvents at
various ratios and temperatures, the polymer recovery was always greater than
94%. The FTIR spectra and the thermal properties (melting point and
crystallinity) of the polymers before and after recycling were measured using
Differential Scanning Calorimetry (DSC). Mechanical properties of the waste
polymer before and after recycling were also measured. Besides small
occasional deviations, the properties did not change. The tensile strength at
maximum load was 7.1, 18.8, and 7.4 MPa for the recycled LDPE, HDPE and PP,
respectively and 7.78, 18.54 and 7.86 MPa for the virgin polymer. For the
waste, the strength was 6.2, 15.58 and 6.76 MPa. |
