Poly(ethylene terephthalate) (PET) and polystyrene (PS) are immiscible and incompatible and have been well recognized. In this study, styrene maleic anhydride random copolymer (SMA-8 wt % MA) and tetra-glycidyl ether of diphenyl diamino methane (TGDDM) are employed as reactive dual compatibilizers i
## Abstract Blends of polystyrene (PS) and polyurethane (PU) elastomer were obtained by melt mixing, using poly(styreneβ__co__βmaleic anhydride) (SMA) containing 7 wt % of maleic anhydride groups as a reactive compatibilizer. Polyurethanes containing polyester flexible segments, PUβes, and polyethe
## Abstract __In situ__ compatibilization of polypropylene (PP) and polystyrene (PS) was achieved by combinative application of tetraethyl thiuram disulfide (TETD) as degradation inhibitor and diβ__tert__βbutyl peroxide as degradation initiator in the process of reactive extrusion. The PP/PS blends
