ABSTRACT:
The present invention relates to compatibilizers useful to laminate a layer of a vinyl aromatic polymer such as polystyrene and a polyester such as PET. The compatibilizer comprises a mixture comprising 5-95 weight % of a polyester, 95-5 weight % of an impact modified polymer of a vinyl aromatic monomer such as high impact polystyrene (HIPS) and from 5 to 20 weight % of a hydrogenated block polymer of a vinyl aromatic monomer and a conjugated diolefin sometimes called SEBS.
