"Concentrated core - shell impact modifier, a mixture of polyester or copoliu00e9ster clear amorphous, articles, and,Process for the preparation of a pellet of concentrate of impact modifier nu00falceo shell "concentrated impact modifiers which produce mixtures transparent.High resistance to impact dynatup, amorphous aromatic polyester, are described.Concentrated impact modifiers amorphous aromatic polyester articles having better clarity than similar articles prepared with impact modifiers pulverized comparable.The concentrated impact modifiers are blends of polyesters with core shell polymers with (a) a core composed mainly of elastic polymers.Such as copolymers of vinyl aromatic diolefinas with monomers such as butadiene copolymer with styrene, (b) an intermediate stage mainly composed of polymers tough.Such as polymers or copolymers of vinyl aromatic monomers.And (c) a shell composed mainly of vinyl aromatic copolymers containing hydroxyl functional groups or their equivalents (e.g., copolymers of styrene / hidroxilaquil (MET) acrylates).
