Macromolecules, 1998•ACS PublicationsCellulation has been observed to develop with increasing radial distance within growing
spherulites of a series of metallocene-catalyzed, ethyl-branched polyethylenes with branch
contents ranging from 14 to 37 per 1000 main chain C atoms. The radius to the onset of
cellulation and the cell width are both sensibly constant for the same polymer and
independent of growth rate. For different polymers, both these quantities fall with increasing
branch content. The implications of these novel findings for the crystallization of polymers …
