Abstract
The surface of incompatible blends of PC with PEO and polystyrene with PEO- polystyrene diblock copolymers with different ratios between the block leng ths was studied by the method of X-ray photoelectron spectroscopy. Due to p hase segregation, the surface of the above blends was found to be enriched with PEO. As was shown, copolymer additives are characterized by a higher c ohesion to a polymer than a pure PEO and produce a surface layer which is m ore stable to ablation with water.
