Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  B | IPC B  C

Claim 0:
1. A composition comprising:
a) a polymer which comprises poly(lactic acid), and
b) an additive,
wherein
the weight percentage of poly(lactic acid) in the polymer is from 60 to 100%,
the weight percentage of the polymer is from 80 to 99.5%, and
the weight percentage of the additive is from 0.5 to 20%,
wherein the weight percentages of the polymer and additive are expressed with respect to the total composition weight, provided that the total sum of the amount of all components in the composition is equal to 100%,
wherein the additive comprises pentaerythritol, dipentaerythritol, tripentaerythritol, tetrapentaerythritol, pentapentaerythritol, and hexapentaerythritol;
wherein
the weight percentage of dipentaerythritol is from 40 to 50%,
the weight percentage of pentaerythritol is from 1 to 20%,
the weight percentage of tripentaerythritol is from 30 to 40%, and
the weight percentage of the sum of tetra-, penta-, and
hexapentaerythritol is from 5 to 20%, wherein the amount of penta- and
hexapentaerythritol is equal to or less than 50% by weight with respect to the sum of tetra-, penta-, and hexapentaerythritol,
wherein the weight percentages are expressed with respect to the total additive weight, provided that the total sum of the amount of the additive in the composition is equal to 100%.
