LIGNIN-BASED POLYMERS WITH ENHANCED MELT EXTRUSION ABILITY

机译:具有增强的熔体挤出能力的基于木质素的聚合物

摘要

A solid polymer blend material comprising: (i) lignin; and (ii) a polyamide having a melting point of no more than 240°C and which is below the decomposition temperature of the lignin; wherein said lignin is homogeneously dispersed in said polyamide. Methods for producing the blend material are also described. Methods for producing objects made of the blend material by melt extrusion are also described, comprising: (a) melt blending components (i) and (ii) to form a polymer blend in which components (i) and (ii) are homogeneously blended, wherein the polymer blend exhibits a melt viscosity of no more than 2000 Pa.s at a shear rate of 100-1000 s-1 and when heated to a temperature of no more than 240°C; and; (b) forming an object made of said polymer blend material.
