Of concern in the present report is the diffusion of homopolmer chains into microphase separated symmetric diblock copolymer hosts. Forward recoil spectrometry was used to study the diffusion of deuterated PS (d-PS) and of d-PMMA into two symmetric diblock copolymer hosts comprised of polystyrene (PS) and polymethylmethacrylate (PMMA). The molecular weight and temperature dependence of diffusion are reported. 4 figs., 13 refs.
