Abstract (en)
[origin: WO2015031315A1] The invention relates to an impact-modified bio-degradable polymer composition having large particle size impact modifiers dispersed in a continuous biodegradable polymer phase. The impact modifiers have a core-shell morphology and may have average sizes of greater than 250 nm. The impact-modified composition has good impact properties and low haze. The biodegradable polymer is preferably a polylactide or polyhydroxy butyrate. The composition comprises 30-99.9 weight percent of degradable polymer and 0.1 to 15 weight percent of one or more impact modifiers.
