SMECTIC ORDERING IN POLY(4-MALEIMIDOCHOLESTERYLBENZOATE), POLY(6-MALEIMIDOCHOLESTERYL-HEXANOATE) AND ALTERNATING COPOLYMERS WITH STYRENE, ALPHA-METHYLSTYRENE AND BETA-METHYLSTYRENE AND PHENYLVINYL ETHYL ETHER

Poly(4-maleimidocholesterylbenzoate), poly(6-maleimidocholesterylhexan oate) and alternating copolymers with styrene, alpha- and beta-methyls tyrene and phenylvinyl ethyl ether are birefringent in polarizing opti cal microscope and show a sharp reflection at 1.49-1.73 nm and an amor phous halo at 0.55-0.57 nm. The absence of discrete reflections in WAX D indicates the smectic ordering, i.e. a frozen-in liquid crystalline phase. At lower angle a reflection at 3.53 nm appears for poly(4-malei midocholesterylhexanoate-alt-styrene) thus indicating that the reflect ion at 1.71 nm is a 2nd order of the true periodicity of 3.5 nm for al l studied polymers.
