摘要： Pure, substantially neutral, low-volatile organic compounds including reactive double bonds are advantageously isolated from a liquid feedstock which contains said compounds in combination with acidic reaction components or auxiliary materials by (i) adding to the feedstock, as neutralizing agents, finely powdered oxides, carbonates and/or hydroxides of the alkali metals and/or alkaline earth metals; (ii) adding, at the same time as the addition of the neutralizing agents or thereafter, a limited amount of water to the mixture of feedstock and neutralizing agents; (iii) mechanically mixing the liquid and solid mixture thus formed for at least a few minutes; (iv) distilling off water from the hot reaction mixture under reduced pressure; and (v) removal from the liquid product of the solid phase now present. Pure products which even without distillation exhibit low residual acid values in combination with low color values result. In a particular embodiment, a process according to the invention is used for an exchange of inhibitors in a mixture reactive when initiated by free radicals; in this exchange, a preparation inhibitor capable of undergoing a salt formation with bases is exchanged for an application inhibitor that may be freely selected with respect to kind and amounts thereof.

The materials and/or shaped articles according to the invention are characterized in that their contents of synthetic thermoplastic polymer compounds is derived from aqueous polymer dispersions comprising a disperse polymer phase in an aqueous phase and that the synthetic thermoplastic polymer compounds have been incorporated in the starch in combination with the aqueous phase in such a manner that the starch digestion has been effected by the concomitant use of the aqueous phase of the polymer dispersions. Said materials and/or shaped articles have been preferably produced by a process wherein the starch digestion to form a thermoplastic material has occurred together with homogeneously mixing the aqueous polymer dispersions into the starch in one process step.

摘要： The invention describes a process for the partial or complete exchange of the free radical inhibitors (preparation inhibitor) from their admixtures with free radical-reactive--and especially polymerizable and/or cross-linkable--olefinically mono- and/or polyunsaturated compounds against free radical inhibitors or inhibitor systems (application inhibitor), the kind and amount of which are freely determinable. The process according to the invention is characterized in that admixtures reactive via free radicals are employed which contain, as the preparation inhibitor, appropriate compounds of the phenol type comprising hydroxyl groups capable of forming salts, this feedstock mixture as a liquid phase is subjected to a treatment with solid oxides, carbonates and/or hydroxides of the alkali metals and/or alkaline earth metals, which may also be present in admixture with further oxidic metal compounds, thereby in a pre-determinable manner binding all or part of the preparation inhibitor to the solid phase, the resulting solid phase is separated from the liquid phase, and the content of the application inhibitor in this liquid phase is adjusted with respect to kind an amount thereof. The process is preferably applied to free radical-reactive substance mixtures, from which the preparation inhibitors contained therein cannot be satisfactorily removed by way of a distillation.
