Abstract
Polylactide resins are blended with core-shell rubber particles to improve impact strength. A good balance of impact strength and transparency is achieved when the rubber particles are distributed within the polymer matrix such that most of them exist as single particles or agglomerates having a diameter of 150 nanometers or more, and the number average size of the particles and agglomerates is not more than 210 nanometers.
