Rheology of Elastomer Blends

Rubber Chemistry and Technology, 1973
Abstract The melt flow properties of certain elastomer blends are shown to be a function of the mixing history and the morphology of the blends. And, more significantly, the melt flow properties are found to be non-additive functions of the melt flow properties of the homopolymers comprising the blends.

Fracture Behavior of Polypropylene /Elastomer Blends

Advanced Materials Research, 2008
In this paper, effort has been undertaken to study the fracture behavior of thermoplastic/elastomer (PP/SBS) dynamically vulcanized blends by analyzing the EWF test results. PP/SBS blends were prepared with concentrations of SBS of 15, 30 and 40 wt%.

Electrically Conductive Polyacetylene/Elastomer Blends

Molecular Crystals and Liquid Crystals, 1984
Abstract Polymer blends of polyacetylene with elastomers such as polybutadiene and thermoplastic elastomers such as the styrene-butadiene-styrene copolymers have been prepared and examined. The resultant blends were charcterized by infrared spectroscopy, thermal analysis, x-ray diffraction techniques, and transmission electron microscopy.

Elastomer Blends

Rubber Chemistry and Technology, 2002
Abstract Blending of elastomers is often used to enhance he performance characteristics of rubber products. This article reviews the thermodynamic principles underlying polymer-polymer miscibility, with special reference to elastomer blends. It discusses the distribution of fillers, additives and curatives in different phases of the blend and ...

Compatibilization of elastomer‐based blends

Macromolecular Symposia, 2002
AbstractThe reactive compatibilization of ethylene‐propylene‐diene (EPDM)‐based dissimilar elastomer blends has been investigated in terms of mechanical properties and swelling degree. The use of mercapto‐functionalized copolymers resulted in an improvement of mechanical properties of natural rubber‐EPDM blends.

Characterization of Immiscible Elastomer Blends

Rubber Chemistry and Technology, 1993
Abstract Considerable improvements have been made in the analysis of elastomer blends for composition, morphology and filler inter-phase distribution. GC, IR, NMR and thermal analysis (DTG, DSC, TG) techniques can provide quantitative information on composition.

Encapsulation in Ternary Elastomer Blends

Rubber Chemistry and Technology, 1999
Abstract Ternary elastomer blends of acrylonitrile-butadiene rubber (NBR), chlorinated polyethylene (CM), and ethylene-propylene rubber (EP) have been investigated using transmission electron microscopy (TEM). Especially the effect of comonomer content, chlorine in CM and acrylonitrile in NBR, on blend morphology is studied.

Reactive Polyolefin Elastomer/Polypropylene Blends

Journal of Polymer Engineering, 2006
Reactive modification of polyolefin elastomer/polypropylene (PP) blends using an organic peroxide initiator is investigated. In the presence of a polyolefin elastomer matrix the crosslinking reaction dominates over the degradation of PP. Partition of the peroxide in the two phases and crosslink density depend highly on the method of incorporation of ...

Polyolefin Thermoplastic Elastomer Blends

Rubber Chemistry and Technology, 1991
Abstract Thermoplastic elastomers based on blends of polyolefins are an important family of engineering materials. Their importance arises from a combination of rubbery properties along with their thermoplastic nature in contrast to thermoset elastomers.

Thermoplastic elastomers based on elastomer/thermoplastic blends dynamically vulcanized

1997
Elastomer—thermoplastic blends have become technologically useful as thermoplastic elastomers in recent years [1–3]. They have many of the properties of elastomers but are processable as thermoplastics [4]. They do not need to be vulcanized during fabrication into end-use parts.
