Abstract

Blending of two or more different polymers makes it possible to achieve various property combinations of the resulting material—mostly in a more cost‐effective way than by synthesis of new polymers. The resulting multicomponent and mostly heterogeneous blends are an extraordinarily important group of polymer materials, which comprise about a third of the world's polymer production. Common features of preparation, evaluation, and application of polymer blends are the main subject of the chapter. The basic problems associated with the nonequilibrium phase structure and its coarsening, the effects of interfacial energy of components, the strategies of compatibilization of immiscible polymers, and methods of phase structure analysis are elucidated. Special attention is paid to mechanical properties of heterogeneous blends and their prediction. Commercially important types of polymer blends as well as recycling of commingled plastic waste are briefly discussed.

  • The most efficient method for improving the toughness of a brittle polymer is blending it with soft, ductile polymers.

    “Generally, most efficient method for an improvement of toughness of a brittle polymer is its blending with soft, ductile polymers (Bucknall, 2000;Horak et al., 2005).”

  • The modulus and yield strength of PLA/PCL blends decrease with the PCL content.

    “As for the stiffness, all studies are in agreement that the modulus and yield strength of PLA/PCL blends decreases with the PCL content.”

  • A compatibilizer can efficiently suppress changes in the phase structure during polymer blend processing.

    “It is also very important that compatibilizer can efficiently suppress changes in the phase structure during polymer blends processing (Macosko et al., 1996;Marić and Macosko, 2002;Horak et al., 2005).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
