Abstract
It is shown that linearized elasticity theory fails for nematic polymers in less than four dimensions. Instead, the polymer osmotic elastic modulus E and the elastic moduli and all become singular functions of wave vector q as ‖q‖→0, with E vanishing like and diverging like . These exponents satisfy an exact scaling relation ++=1 in three dimensions, and are calculated to second order in ɛ=4-d, yielding =0.46±0.015, =0.28±0.015, and =0.21±0.015 in d=3.
