Dispersivity of rubbers in thermoplastic polymers
The main factors influencing the dispersivity of rubbers (nitrile and ethylene–propylene) in nylon 6 (PA‐6) and polypropylene (PP) are investigated. On the basis of an equation, describing the influence of interfacial tension and viscosity ratio of disperse and matrix phases on the average size of d...

Summary: | The main factors influencing the dispersivity of rubbers (nitrile and ethylene–propylene) in nylon 6 (PA‐6) and polypropylene (PP) are investigated. On the basis of an equation, describing the influence of interfacial tension and viscosity ratio of disperse and matrix phases on the average size of dispersed phase particles, analysis of dispergation process in researched blended systems has been conducted. The limits of applicability of a given equation were established. It was shown that the best dispersivity of rubbers in the PA matrix is observed in that case when the viscosity values of initial components of a blend are close to each other. © 1999 John Wiley & Sons, Inc.
