The aim of this work was to study the activity of several alkylimidazolium salts of bis(trifluoromethylsulfonyl)imides to obtain a very fast vulcanization of the butadiene-styrene (SBR) elastomer. Ionic liquids (ILs) such as alkylimidazolium salts with ethyl-, propyl-, butyl-, hexyl-, decyl-, dodecyl-, and hexadecyl chains in the cation together with nanosized zinc oxide are used to develop elastomer composites with very short vulcanization time and a reduced amount of vulcanization activator. In this article, we discuss the effect of the ILs with respect to the length of alkyl chain in their cation on the vulcanization kinetics of rubber compounds. The influence of ILs on the crosslink density as well as the mechanical properties of the vulcanizates and their resistance to thermo-oxidative and UV aging were also studied. ILs resulted in a shortened optimal vulcanization time and reduced the onset vulcanization temperature compared to zinc oxide containing rubber compound. This is very important from a technological point of view. A considerable increase in the crosslink density of vulcanizates was also observed.

Ionic liquids (ILs) are organic salts that are liquid at ambient temperatures. ILs are considered a versatile class of chemicals because their properties can be easily tailored for specific applications. Due to their negligible vapor pressure, non-flammability, and thermal stability in the temperature range for preparation and processing of elastomeric composites, ILs are being used increasingly in the field of elastomer science and technology. In this review, the advantages of ILs as functional additives for elastomeric composites are discussed, with special emphasis on their use as dispersing agents for fillers, components of conducting rubber composites, crosslinkers or components of crosslinking systems.

“…8,9 The thermodynamic incompatibility between so and hard segments leads to phase separation which is formed owing to molecular structure and mole ratio of composition. 10,11 The degree of phase separation signicantly affects mechanical and thermal properties of PUE. [14][15][16][17] The properties of PUE can be adjusted through changing the composition and the mole ratio of hard and so segments during synthesis or through incorporation of a ller into the PUE matrix.…”

A novel ionomeric polyurethane elastomer based on ionic liquid as crosslinker

Abstract: A novel flexible polyurethane was prepared using ionic liquid as crosslinker. It showed lower Tg, superelastomeric behavior with very high elongation, better tensile and oil resistance properties than a non-ionic crosslinked PU or a linear PU.
