Abstract Thermally conductive polymers have gained scientific attention for improving heat dissipation in electric devices. Their thermal conductivity is enhanced by optimizing the network molecular alignment. Liquid crystal, through intermolecular interaction, achieves high orientation levels, thereby enabling superior conductivity. This study aims to demonstrate of derived from liquid crystal materials synthesizing a series monomers, EP n , based on phenyl benzoate mesogen core. The monomers are designed with epoxide functional groups various alkyl chain tails ( = 3, 4, 5, 8). Side‐chain polyethylene glycols (P‐EP series) synthesized anionic ring‐opening polymerization using potassium tert ‐butoxide. effect introduced aliphatic tail structural and physical properties investigated, revealing significant effects phase transition behavior In addition, P‐EP exhibits higher decomposition temperature (> 360 °C) compared conventional glycol, 5 achieving highest 0.42 W m −1 K series.
