摘要：

Motional heterogeneity in acrylate (AA)/laurylmethacrylate (LMA) copolymers was investigated by the two-dimensional H-1-C-13 heteronuclear widline-separation n.m.r. technique. Qualitative information about molecular dynamics is reflected in the width of the proton wideline. It was found that a decrease of the AA/LMA ratio in the copolymer reduces the packing density.
