MOLECULAR DESIGN OF MULTICOMPONENT POLYMER SYSTEMS - 3. COMPARATIVE BEHAVIOR OF PURE AND TAPERED BLOCK COPOLYMERS IN EMULSIFICATION OF BLENDS OF LOW-DENSITY POLYETHYLENE AND POLYSTYRENE.
[en] Poly(hydrogenated butadiene-b-styrene copolymers are very effective emulsifiers for blends of polystyrene and low-density or high-density polyethylene. It is shown that the extent of improvement in mechanical properties is dependent not only on the molecular weight but also on the structure of the diblock copolymer. A comparative study of the morphology and the mechanical behavior of modified low-density polyethylene/polystyrene blends demonstrates that a tapered diblock is more efficient than a pure diblock with the same composition and molecular weight. It is assumed that the unique behavior of the tapered sample results from its particular miscibility characteristics at the blend interface. The tapered copolymer could behave essentially as a solubilizing agent for the homopolymers at the interface and provide a ″graded″ modulus responsible for the improved mechanical response of the material.
