Abstract

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 ##STR1## in which R.sub.1 is hydrogen or an alkyl group with 1 to 18 carbon atoms, PA1 R.sub.2 is hydrogen or an alkyl group with 1 to 6 carbon atoms, and PA1 R.sub.3 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.
