Promising Mechanical Properties in the Present Biobased Polyesters Beyond Polyethylene

Caption

Effect of molecular weight toward tensile properties in the present biobased polyesters, HP1. The plots of PE-18,18 (polyester-18,18, reported biobased), and commercially available polyethylene terephthalate (PET), poly(lactic acid) (PLA), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and polystyrene (PS) are placed for comparison. In general, polymer films exhibiting higher tensile strength (with increase of molecular weight) tends to decrease the elongation at break.  The present high molecular weight biobased polyester (HP1), achieved in this study, shows promising tensile properties (tensile strength, elongation at break) beyond commodity plastics. The success was enabled by synthesis of high molecular weight polymers by high performance molecular catalyst.
