Patent ID: 8389614

Claim:
A composition made from starting materials comprising: between 20% and 97% by weight of poly(lactic acid) polymer (PLA) on the basis of the total weight of the polymer composition; between 0.5% and 65% by weight of a co-polyester polymer with adipic acid on the basis of the total weight of the polymer composition; and between 0.01% and 6% by weight of nanoparticles of a mineral material on the basis of the total weight of the polymer composition, the mineral material being selected from the group consisting of silica, nanoclays of the vermiculite family, and combinations thereof, wherein the nanoparticles have a size ranging between 20 and 500 nanometers, and wherein the nanoparticles of the mineral material have a degree of purity of at least 99.9%.
