Description

Poly(maleic anhydride) was reacted with long-chain aliphatic amines in a 1:1 molar ratio (as per monomer unit) resulting in the formation of amphiphilic polymers bearing the carboxylic group on their polymer backbone. On the other hand, poly(acryloyl chloride) was interacted with ω-amino or ω-hydroxy carboxylic acids affording polyamphiphiles with the carboxylic polar group at the tail of the pendant group. In addition, the carboxylic group was replaced by the extremely polar quaternary group at the end of the lipophilic chain. Liquid crystalline textures were exhibited by these polymers as determined by optical microscopy and d.s.c. studies while the supramolecular structures, formed through hydrogen bonding of carboxylic groups, were responsible for the formation of mesomorphic phases. © 1992.
