Factors influencing the efficacy of an interfacial modifier for the interface in an immiscible polymer blend

摘要

The modification of the interface in immiscible polymer blends is critical in order to optimize physical properties. Despite the great commercial importance of polymer blends, many aspects of the emulsification process remain unclear. In this paper, it will be shown that an emulsification curve can be used to estimate the influence of the architecture and molar mass of styrene/hydrogenated butadiene block copolymer interfacial modifiers on the emulsification of poly- styrene/ethylene-propylene rubber blends under melt processing conditions.
