We have performed measurements of the static structure factor S(Q) on Polye
thylmethacrylate and Polyhexylmethacrylate on ROTAX at ambient T in the Q-r
ange 0.5 < Q/Angstrom(-1) < 4.5 and on the DNS spectrometer at T = 8 K in t
he Q-range 0.1 < Q/Angstrom(-1) < 3.2 thereby including spin polarization a
nalysis. Each polymer was either deuterated at the side (-ester) chain or a
t the main chain giving rise to vastly different partial structure factors.
Possible correlations to the structure are given. (C) 2000 Elsevier Scienc
