METHOD OF RECYCLING OF COMMINGLED PLASTICS WASTE TO TOUGH THERMOPLASTIC MATERIALS

摘要

The application concerns the method of recycling commingled plastics wastecontaining min. 30 wt. % of polyolefins to a tough thermoplastic material. Themethod is based on the compatibilization of the polymer components ofcommingled plastics waste with an admixture of 2 - 15 wt. % of an ethylene -propylene copolymer or a styrene - butadiene block copolymer or a combinationof an ethylene - propylene copolymer and a styrene - butadiene copolymer inany weight ratio, together with 0.1 - 2.5 wt. % of a secondary aromatic amineand by subsequent blend processing in the melt.
