Patent ID: 7300978

Claim:
A process for stabilishing and at the same time phase compatibilising plastic compositions comprising at least two different polymers by incorporating a ploymeric compound obtained by reacting a sterically hindered phenol which compound contain at least one reactive group with a compatibiliser, wherein the compatibiliser compound is a grafted styrene co- or terpolymer selected from the group consisting of styrene/acrylonitrile grafted with maleic anhyclride (SAN-g-MAH), styrene/maleic an hydride/methyl methacrylate, styrene/butadiene/styrene block copolymer grafted with maleic anhydride (SBS-g-MAH), styrene/ethylene/propylene/styrene block copolymer grafted with maleic anhydride (SEPS-g-MAH), styrene/ethylene/butadiene/styrene block copolymer grafted with maleic anhydride (SEPS-g-MAH) and acrylic acid/polyethylene/polystyrene terpolymer (AA-PE-PS-terpolymer).
