HIGH STRENGTH LIGNIN-ACRYLONITRILE POLYMER BLEND MATERIALS

摘要

A polymer blend material comprising: (i) a lignin component; (ii) a nitrile butadiene rubber component; and (iii) divalent or trivalent metal sa wherein: component (i) is present in an amount of about 5 wt. % to about 95 wt. % by weight of components (i) and (ii); component (i) is dispersed in component (ii) in the form of domains having a size of up to 1000 nm; component (iii) is present in an amount of 0.1-10 wt. % by weight of components (i) and (ii); and the polymer blend material has a tensile failure strength of at least 10 MPa, and an elongation at break of at least 20%. Methods for producing the polymer blend, molded forms thereof, and articles thereof, are also described.
