PURPOSE: A maleimide group thermosetting liquid crystal composition is provided to improve solvent solubility, liquid crystal orientation of mesogen, moldability, and processability. CONSTITUTION: A maleimide group thermosetting liquid crystal composition comprises a liquid crystal thermoset monomer having a structure of chemical formula 1. In chemical formula 1, R1 and R2 are selected from hydrogen, a methyl group, and an ethyl group, respectively. Ar1 and Ar2 are a mesogenic group and Q is an alkyl flexible group. The composition further includes an aprotic solvent. The aprotic solvent is selected from N,N-dimethyl acetamide, N-methyl pyrrolidone, N-methyl caprolactam, N,N-dimethyl formamide, N,N-diethyl formamide, N,N-diethyl acetamide, N-methyl propionamide, dimethyl sulfoxide,γ-butyl lactone, dimethyl imidazolidinone, tetramethyl phosphoric amide, and ethyl cellosolve acetate. |
