1. A composition comprising rubber and
(i) poly alpha-1,3-glucan, wherein the percentage of glycosidic linkages of the poly alpha-1,3-glucan that are alpha-1,3 is greater than or equal to 50%, or
(ii) a poly alpha-1,3-glucan ester compound represented by Structure I:

OG Complex Work Unit Chemistry
wherein
(A) n is at least 6,
(B) each R is independently an —H or a first group comprising —CO—Cx—COOH, wherein the —Cx— portion of said first group comprises a chain of 2 to 18 carbon atoms,
(C) the poly alpha-1,3-glucan ester compound has a degree of substitution with the first group of about 0.001 to about 3.0, and
(D) the percentage of glycosidic linkages of the poly alpha-1,3-glucan ester compound that are alpha-1,3 is greater than or equal to 50%;
wherein the rubber comprises at least one diene-based sulfur-vulcanizable or peroxide-vulcanizable elastomer.
