摘要: A new class of linear unsaturated polyarylphosphate esters based on dibenzylidene cyclopentanone, possessing liquid crystalline‐cum‐photocrosslinkable properties has been synthesized from 2,5‐bis(m‐hydroxyalkyloxybenzylidene)cyclopentanone (m = 6,8,10) with various aryl phosphorodichloridates (aryl = phenyl, naphthyl, biphenyl) in chloroform at ambient temperature. Their chemical structures were confirmed by FTIR, and 1H, 13C 31P NMR spectroscopy. Intrinsic viscosity showed that all the polymers materials moderate molecular mass. Phase behaviour was investigated differential scanning calorimetry hot stage polarizing optical microscopy, under which anisotropic behaviour. The T m i decreased increasing flexible methylene chain polymer backbone. thermal studied thermogravimetric analysis, their photocrosslinking UV crosslinking proceeds via 2...
