Aggregation of methylcellulose in aqueous dilute solution is studied by light and small angle neutron scattering. For temperature T<293.15K, the free chains adopt a swollen conformation. For T>313.15K, a slow aggregation kinetics occurs. At qR g <1, the association number is found to vary as R g 3 . However at qR g >1, the scattered intensity decreases as q −(1
