Ionomics and the Study of the Plant Ionome
Annual Review of Plant Biology, 2008The ionome is defined as the mineral nutrient and trace element composition of an organism and represents the inorganic component of cellular and organismal systems. Ionomics, the study of the ionome, involves the quantitative and simultaneous measurement of the elemental composition of living organisms and changes in this composition in response to ...

Redox active LC ionomers: LC ionomers as materials for compatible blends with amorphous ionomers
Acta Polymerica, 1995AbstractRedoxactive liquid crystalline (LC) side group polymers were prepared by copolymerization of liquid crystalline acrylates and ferrocene‐containing acrylates. The corresponding liquid crystalline ionomers were synthesized by a reversible redox reaction.

Journal of Polymer Science Part A: Polymer Chemistry, 1989
AbstractThe preparation and properties of highly crystalline ionomers formed by the copolymerization of propylene and low levels of ethylcholoroaluminium 10‐undecenoate have been investigated. Few of the variables studied had dramatic effects on the copolymerization. Thus, a five‐fold increase in undecenoate concentration gave only about a 20% increase

Abstract Ionomers are a class of materials which are emerging as important commercial polymers but yet have many intriguing scientific characteristics. Typically, ionomers consist of a low level of inorganic salt groups pendent to a polymer chain.

British Polymer Journal, 1975
AbstractThe chemistry and properties of the ionomer cements are reviewed. These cements are defined by the acid‐base interaction between metal oxides or silicates with aqueous solutions of organic polymeric acids. the cements formed both from ion‐leachable aluminosilicates and from zinc oxide are of practical importance and characterised by their ...

Progress in Rubber and Plastics Technology, 1991
Two types of urethane ionomers (cationomers and anionomers) were prepared and their structure - properties relationships examined. The mechanical properties and glass transition temperatures (Tg) of urethane cationomers increased with decreasing molecular weight of the polyols, and increasing concentrations of quaternary ammonium ions and degree of ...

Ionomer Solutions = Polyelectrolyte or Ionomer Behavior?
1994For almost ten years the properties of ionomer solutions have been studied and lightly sulfonated polystyrene (S-PS) was chosen as the model compound. The properties of S-PS ionomer solutions in polar and nonpolar solvents, which are briefly reviewed, were associated with polyelectrolyte and ionomer behavior respectively.
