| 摘要 |
This invention relates to a process for the production of a thermoplastic synthetic material of chemically modified protein, which comprises mixing an aqueous alkaline protein solution with an aqueous solution of a tetrafunctional, doubly unsaturated, organic compound of the general formula <IMAGE> in which R1 is hydrogen or an alkyl group with 1 to 18 carbon atoms, R2 is hydrogen or an alkyl group with 1 to 6 carbon atoms, and R3 is hydrogen or an alkyl group with 1 to 3 carbon atoms, SUBJECTING THE MIXTURE TO A DWELL TIME, CAUSING A PRECIPITATING LIQUID TO ACT UPON IT, FREEING THE FORMED PRECIPITATE FROM EXCESS LIQUID, AND DRYING. The invention also relates to a shaping material of plastic material of chemically modified protein and a chemical plasticizer. The invention also relates to a plastic material of modified protein. |
