Abstract: The invention relates to a new method for improved distribution of a substance or mixture of substances in a carrier or substrate or in a mixture of different carriers or substrates. The invention likewise relates to the raw, multicomponent compositions, semi-finished products or end articles obtained by this method and also to the micropowders of the substance or mixture of substances that are used in the method. The invention relates in particular to the application of this method to the incorporation of additives into plastics and to the plastics additives micropowders prepared for that purpose.
