Abstract The modified polyurethane elastomer material is prepared by mixing nitrolignin, castor oil type polyurethane, chain expander, 1,4-bytanediol and solvlent tetrahydrofuran and curing at proper condition. Compared with existing polyurethane, the modified polyurethane has obviously raised tensile strength and extension at break, and it has elasticity of restoring deformation completely similar to that of rubber and may be biologically degraded. It may be used as biologically degraded paint and film material in medicine, daily use, chemical industry, environment protection and other fields.
