Claim 0:
1. A thermoplastic acrylonitrile containing copolymer/lignin blend comprising:
(i) an amount of lignin, wherein the lignin is selected from a kraft lignin, a sulfite lignin, a sulfur-free lignin, or combinations thereof and sourced from a hardwood or softwood feedstock;
(ii) an amount of a thermoplastic acrylonitrile containing copolymer, wherein the thermoplastic acrylonitrile containing copolymer is a first acrylonitrile-butadiene-styrene copolymer; and
(iii) an amount of a compatibilizing agent, wherein the compatibilizing agent includes at least a dianhydride, and a second acrylonitrile, butadiene and styrene copolymer having a butadiene content of at least 50% by weight, which is a different copolymer than the first acrylonitrile-butadiene-styrene copolymer, and
wherein the lignin is present in an amount from about 5 to 50 wt % by total weight of components (i) and (ii), components (i) and (ii) are present together in an amount from 75 wt % or greater by weight of the total weight of the blend, and the compatibilizing agent comprises from about 0.5 to 25% by weight of the total weight of the blend.
