FIELD: chemistry.
SUBSTANCE: functional filler for polymeric compositions comprises an inorganic dispersed material and a coating, comprising a compound having the formula: A-(X-Y-CO)m(O-B-CO)nOH (1), where A is a fragment having terminal olelinic link, with one or two adjacent carbonyl groups; X is O and m equals 1-4 or X is N and m equals 1; Y is C1-18-alkylene or C2-18-alkenylene; B is C2-6-alkylene; n equals 0-5. When A comprises two carbonyl groups adjacent to the ethylene group, X represents N. The inorganic dispersed material has d50 less than about 10 mcm.
EFFECT: invention enables to obtain articles made of compositions of high quality recycled polymers by reduction of evolving unpleasant odour from polymer wastes subjected to regeneration.
