## Abstract ^13^C solid‐state exchange NMR is applied to study the influence of morphology on chain diffusion between crystalline and noncrystalline regions in ultrahigh molecular weight linear polyethylene (PE). Lamellar‐doubling reduces the exchange rate by a factor of two indicating that the cha
