An elastomeric composition, contains:—at least 5% and at most 70% by weight of an ester of a starchy material, which has a degree of ester substitution (DS) of between 1.0 and 3.0, preferably between 1.2 and 3.0,—at least 5% and at most 40% by weight of a plasticizer of this ester of starchy material, the plasticizer preferably being other than water, and—at least 25% by weight and at most 90% by weight of an elastomeric non-starch polymer. |
