Polymers have an important role in our daily lives and a large amount of polymers produce
each year. Polymers have many advantages e.g. Less weight, higher energy efficiency,
performance and durability and more flexibility in design and processing [1]. Poly(ionic liquid)s
(PILs), are compounds that have an IL species in each monomer repeating unit, that are connected
to the polymer backbone and can be afforded through polymerization of IL containing
polymerizable groups either in cation or anion, or chemical modification of other polymers. Due
to their chemical structure (polymers containing repeating cationic and anionic units that are an
electrolyte group), also called poly electrolytes [2]. Styrene is one of the most chemicals that has
a wide range of applications from food packaging to automobile segments [3], so much of
research is focused on enhancing the properties of polystyrne. In the present work, the styrenic IL
monomers based on 1-Methylbenzotriazolium cation were synthesized by linking the 1-
Methylbenzotriazol to VBC, then new styrenic ionic liquid based PILs (Figure 1.) were prepared
with the free radical polymerization method. The structure of PILs were characterized by IR
and1HNMR data.Study of thermogravimetric analysis, and differential scanning calorimetry data
showed that the resulting polymers have excellent thermal stability. Solubility of homopolymers
in different organic solvents was tested and the electrochemical window of their was investigated
for comparison with polystyrene. The styrenic ionic liquid based PILs with the advantage of
facile synthesis and the ability to incorporate many desirable functional moieties offer an efficient
route to highly functional styrenic PILs.
