Ferroelectric liquid crystalline (FLC) elastomer as a class of electroactive polymers, exhibiting high strain at very low voltage compared to other materials. This giant eletrostriction exploring new applications for ferroelectric materials and these materials are suitable candidates for designing nanoscale artificial muscles, sensors, actuators, pumps and motors. Due to these properties, considerable attention has been paid to these materials in recent years. In this study, ferroelectric liquid crystalline (FLC) monomer was synthesized in a mini reactor in a four‐step procedure. The synthesized materials were characterized with HNMR and FTIR in each step. Then the monomer in the presence of benzoylperoxide as an initiator and n‐butyl acetate as a solvent was grafted onto polybutylacrylate. Grafting was carried out in different processing conditions and products were characterized with HNMR and DSC. The level of initiator, method of initiator's injection to reactor, reaction time, and reactants concentration were part of parameters that were investigated. The analysis of results shows that the reaction time is an important parameter and appropriate grafting needs a long time. Components concentration illustrated important effect on the level of grafting and final structure of grafted chains.
