MULTIFUNCTION-COMPATIBILISATION PACKAGE OF ADDITIVES FOR PLASTIC AND RUBBER COMPOSITIONS

The invention relates to the low molecular weight compatibilizing additive package having many advantageous effects, which improves the compatibility of different thermoplastic and/or thermosetting polymers and/or fillings, functional additives just as composites containing natural and/or artificial strengthening fibres, and relates to its preparation and application processes. It has been found, that selective grafting of highly reactive α-olefins having C20-C40 average carbon number or hydrocarbon polymers containing more than 80% α-olefins and having an average molecular weight significantly lower than usual ( Mn 3000), with highly reactive monomers or their mixtures, then further chemical modification of the functional groups of the prepared intermediates, just as its simultaneous application with unsaturated fatty acid ester-dicarboxylic acid adduct of high acid number, or its ester-, ester amide-, amide-, or imide derivatives result in products being different in structure from the known compatibilizing additives.
