Abstract: The present invention relates to a polymer composition comprising: (a) a propylene- based polymer having a melt mass-flow rate of ≥ 5.0 and ≤ 90.0 g/10 min, preferably ≥ 10.0 and ≤ 50.0 g/10 min, as determined in accordance with ASTM D1238 (2013) at 230°C under a load of 2.16 kg; and (b) ≥ 5.0 and ≤ 30.0 wt%, with regard to the total weight of the polymer composition, of an ethylene-based polymer having: • a melt mass-flow rate of ≥ 3.0 and ≤ 30.0 g/10 min, as determined in accordance with ASTM D1238 (2013) at 190°C under a load of 2.16 kg; • a density of ≥ 840 and ≤ 870 kg/m3, as determined in accordance with ASTM D792 (2008); and • a content of ≥ 25.0 and ≤ 50.0 wt% of moieties derived from 1-octene, with regard to the total weight of the ethylene- based polymer. Such polymer composition demonstrates improved low temperature impact strength, determined as Izod impact strength at -40 °C and/or at -30°C, as well as desirable toughness, determined as tensile modulus, whilst having good flowability in injection moulding and thereby allowing complex, thin-walled objects to be shaped.

Abstract: A biodegradable bioplastic composition of from 80 wt% to 95 wt% of a polymer having one or more thermoplastic polyester polyhydroxyalkanoates (PHA) and from 5 wt% to 20 wt% an organic dispersed within the polymer. The biodegradable bioplastic composition is devoid of petrochemically derived components, fossil fuel derived components, processing aids, and plasticizer additives. A process is also disclosed for preparing the biodegradable bioplastic composition. The process involves compounding one or more thermoplastic polyester polyhydroxyalkanoates (PHA) and an organic to form a mixture and homogenizing the mixture. Homogenizing includes feeding the mixture to a first extruder and extruding the mixture to form a composite composition and feeding the composite composition to a second extruder and extruding the composite composition to form the biodegradable bioplastic composition.
