Research Abstract

A wood chemically modified by cyanoethylation (CE-wood) demonstrated thermalflow, and the thermoplasticity and solubility of CE-wood were dramatically improved by slight chlorination. Thus, this chemically modified wood could be molded into many shapes like a thermoplastic polymer.
It was the aim of this project to develop high-performance materials derived from chemically modified wood. The results were obtained as follows ;
1. A latex of CE-wood was prepared by the phase-separation method using aqueous-organic polymer solution but without any emulsifier. The viscosity of the latex was as low an one-tenth of that a dimethylformamide solution of CE-wood.
2. CE-wood was plasticized effectively by blending with CE-poly (vinyl alcohol). CE-wood which contained lignin showed very high values of dielectric constant comparable to those of CE-cellulose which was well known to be a high dielectric material.
3. Wood was readily converted to a water soluble material with a high content of amide group by cyanoethylation followed by carbamoylethylation.
4. We could make a fiberboard by auto-hesion of a thermally melted-fibers, when the surface cyanoethylated wood-fibers were hot-pressed. It was found that the thermoplasticity and solubility of chemically modified wood were improved by adding a small amount of a metal halide.
5. The miscibility between hemicellulose and lignin, and the effect of the addition of lignin-carbohydrate complex (LCC) to it were studied. It was found that the binary-blends system of hemicellulose and lignin was not miscible, but that it became miscible at high temperature with the addition of LCC.
