Abstract: A polymeric material comprising a first polymer and a second polymer where the first polymer is a natural or a synthetic polymer and the second polymer is modified lignin. The modified lignin is modified with an alkyl containing group via linker wherein the linker is an ether group and wherein the alkyl containing group is derived from fatty acid methyl ester.
