Modeling of tensile properties of polymer blends: PPO/poly(styrene‐co‐p‐chlorostyrene)

Blending polymers is an effective method to develop novel materials, tailoring the properties of the components. However, different morphology structures can be formed during the preparation, which could result in a wide diversity of mechanical and physical properties. The properties of polymer blends are most significantly influenced by the emerging range of phase inversion, which depends on the composition ratio and the viscosity ratio. In this paper various blends were prepared, utilizing polyethylene terephthalate (PET), polystyrene (PS) and two high density polyethylenes (HDPE), which differ in flowability. After preliminary homogenization by twin screw extruder, standard injection moulded specimen were prepared in order to present the effects of phase inversion on tensile properties, shrinkage and burning characteristics in binary polymer blends.

Nylon 6/PET (polyethylene terephthalate) polymer blends (PET varying from 10–50%) were melt spun into fibers. Their tensile properties (at room temperature) and dynamic mechanical properties (at 110 Hz from room temperature to 200°C) were studied. An increase in the initial modulus with increasing PET content was observed. The tenacity showed an increase and then a subsequent decrease after 70/30 nylon 6/PET composition. The blend fibers showed lower extensibility. Various theories connecting modulus and tenacity (independently) with composition, interfacial adhesion, and dispersed phase morphology helped to explain the observed tensile properties. The loss tangent maxima is shifted to a higher temperature with increased PET content in the blend fiber, while the relaxation peaks become broader up to a certain composition. Further, the storage modulus increases throughout with the increase in the PET content. The Takayanagi series and parallel models have been applied, and the results describe the structural and morphological features of the blend fiber, besides explaining some of the properties.

Development Application

Core edge spectroscopy methods are versatile tools for investigating a wide variety of materials. They can be used to probe the electronic states of materials in bulk solids, on surfaces, or in the gas phase. This family of methods involves promoting an inner shell (core) electron to an excited state and recording either the primary excitation or secondary decay of the excited state. The techniques are complimentary and have different strengths and limitations for studying challenging aspects of materials. The need to identify components in polymers or polymer blends at high spatial resolution has driven development, application, and integration of results from several of these methods.

A Domains

Two new morphological measurements based on digital image analysis, CoContinuity and CoContinuity Balance, have been developed and implemented for quantitative measurement of morphology in polymer blends. The morphology of polymer blends varies with phase ratio, composition and processing. A typical morphological evolution for increasing phase ratio of polymer A to polymer B starts with discrete domains of A in a matrix of B (A/B < 1), moves through a cocontinuous distribution of A and B (A/B ≈ 1) and finishes with discrete domains of B in a matrix of A (A/B > 1). For low phase ratios, A is often seen as solid convex particles embedded in the continuous B phase. As the ratio increases, A domains begin to evolve into irregular shapes, though still recognizable as separate domains. Further increase in the phase ratio leads to A domains which extend into and surround the B phase while the B phase simultaneously extends into and surrounds the A phase.
