Abstract
A composition that includes the reaction product of a lignin derivative and a reactant selected from the group consisting of alkylating agents, acylating agents, and combinations thereof, where the reaction product has a measurable cohesive strength, and a plasticizer in an amount sufficient to cause the composition to exhibit plastic deformation in response to an applied tensile stress.
