ABSTRACT OF THE DISCLOSURE This invention relates to a process for the production of a thermoplastic synthetic material of chemically modified protein, which com- prises 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 pre- cipitate 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. The plastic material can be used in, for example, buttons, combs, trinkets, umbrella handles, piano keys and similar articles.
