Abstract (en)
[origin: WO2007063361A1] A biodegradable polymer composition useful for manufacturing biodegradable items or articles with improved mechanical properties comprising poly(lactic acid) polymer (PLA), starch and protein material, obtainable by providing poly(lactic acid) polymer (PLA), starch and protein material in such ratios that PL A/starch blend represents at least 95% weight of the above three components and that starch represents at least 23% weight of PLA; mixing the above three components at room temperature in a controlled moisture atmosphere to afford a homogeneous mixture; subjecting the above homogeneous mixture to extrusion compounding under controlled heat, speed and pressure conditions; and drying down to a maximum of approximately 1% weight of moisture and subsequently conditioning the extruded polymeric composition.
