Provided is an antistatic agent (Z) containing: a block polymer (A) having a block of a hydrophobic polymer (a) and a block of a hydrophilic polymer (b) as structure units; and a sulfonate (S), the sulfonate (S) being a salt of an alkylbenzenesulfonic acid anion which has a C6-C18 alkyl group, the sulfonate (S) including at least two alkylbenzenesulfonates different in the number of carbon atoms of the alkyl group in the anion, the sulfonate (S) satisfying the following formula:

0.40≤W(n)/[W(n−1)+W(n)+W(n+1)]≤0.90

wherein n is the number of carbon atoms of the alkyl group in the anion of an alkylbenzenesulfonate accounting for the highest proportion by weight in the sulfonate (S); W(n) is a weight of said alkylbenzenesulfonate; and W(n−1) and W(n+1) are respectively a weight of an alkylbenzenesulfonate containing an anion having an alkyl group with (n−1) carbon atoms and a weight of an alkylbenzenesulfonate containing an anion having an alkyl group with (n+1) carbon atoms.

Disclosed are biodegradable polyester polymers comprising lignin-containing segments and vegetable-oil based segments. Also disclosed herein are methods of making biodegradable polyester polymers and the articles made from these polymers.
