Abstract
An olefinic polymer composition comprising at least one polyolefin, as well as a broadleaf tree lignin with pH below 7. The invention further relates to objects obtained from such a composition, and the use of broadleaf tree lignin with pH below 7 in the preparation of an olefinic polymer composition.
Claims16
An olefinic polymer composition comprising at least one polyolefin and a eucalyptus lignin with a pH 7 from 3 to 6, wherein the polyolefin consists of polypropylene, wherein the lignin content is from 5% to 30% of the total weight of the composition, wherein the olefinic polymer composition has increased tensile stiffness and melt flow index (MFI) when compared to a pure polypropylene, and wherein the lignin is Kraft lignin.
An olefinic polymer composition comprising at least one polyolefin and a eucalyptus lignin with a pH from 3 to 6, wherein the polyolefin consists of polyethylene, wherein the lignin content is 30% of the total weight of the composition, wherein the olefinic polymer composition has increased tensile stiffness and melt flow index (MFI) when compared to a pure polyethylene, and wherein the lignin is Kraft lignin.
