Abstract:
The invention provides a composition exhibiting improved impact resistance at low levels of impact modifier. The composition comprises a polyhydroxyalkanoic acid and: (A) an elastomeric compound of core-shell type wherein the amount of (A) is from 0.1 to 6% by mass of the composition; and (B) and an olefinic copolymer comprising an ethylenic monomer bearing an epoxy function; wherein the amount of (B) is from 0.01 to 0.6% by mass of the composition and the mass ratio of (A)/(B) is from 85/15 to 99.5/0.5.
