| 摘要 |
The invention relates to a blend of one or more biodegradable polymers with one or more impact modifiers, for the purpose of improving the impact properties of the biodegradable polymer(s). 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. Haze levels can be controlled by the composition and percentage of impact modifier (or modifiers) selected, to produce a polymer composition having an appearance ranging from translucent to opaque. |
