Abstract
The backbone conformation of two different ''side-on fixed'' liquid cr ystalline polyacrylates is studied by Small Angle Neutron Scattering e xperiments in the nematic phase. We observe the influence of a very la rge spacer and a large aliphatic extremities length on the prolate ani sotropy of the polymer backbone. In both situations we find a strong d ecrease in the conformation anisotropy of the main chain.
