Liquid crystal polymers copolymers and elastomers containing a laterally attached mesogenic unit
Whale, Eric A.,Davis, Frederick J.,Mitchell, Geoffrey R.
, p. 1479 - 1485 (1996)
The synthesis of a closely-coupled laterally attached side-chain liquid crystal polymer is described. The material exhibits liquid crystalline behaviour over a wide temperature range. Incorporation of non-mesogenic methyl acrylate as a comonomer with the
Selective reduction of 2-[(benzoyl)oxy]benzaldehydes without intramolecular transesterification
Pugh, Coleen

(equation presented) NaBH4 reduction of 2,5-bis[(4′-(n-alkoxy)benzoyl)oxy]benzaldehydes produces primarily the rearranged phenol, which does not generate liquid crystalline phases when laterally attached to a polymer backbone. Rearrangement is prevented by quenching the intermediate benzyl alkoxide with a weak acid. For example, 2,5-bis[(4′-(methoxy)benzoyl)oxy]benzaldehyde is selectively reduced to 2,5-bis[(4′-(methoxy)benzoyl)oxy]-benzyl alcohol with less than 5% intramolecular transesterification using 2-3 equiv of NaBH4 in the presence of 20-30 equiv of acetic acid (1:10 NaBH4/AcOH).
Synthesis of 2,5-(4-alkoxybenzoyloxy)benzyl acrylates and cinnamates, monomers for side chain liquid crystal polymers

Abstract: A variety of 2,5-(4-alkoxybenzoyloxy)benzyl acrylates and cinnamates, which can serve as monomers for side chain liquid crystal polymers, were readily synthesized from hydroquinone. Instead of the rare and expensive 2,5-dihydroxybenzaldehyde, ch
SYNTHESIS OF A NEW CLASS OF SIDE CHAIN LIQUID CRYSTAL POLYMERS. POLYMERS WITH MESOGENS LATERALLY ATTACHED VIA SHORT LINKAGES TO POLYMER BACKBONES
Zhou, Qi-Feng,Li, Hui-Min,Feng, Xin-De
, p. 73 - 82 (2007/10/02)
New monomers, 2,5-(4-alkoxybenzoyloxy)benzyl acrylates were synthesized.Upon radical polymerizations of these monomers thermotropic liquid crystalline polyacrylates with mesogens laterally attached to polymer backbones via short linkages were obtained.The
