XRD measurements for crystals of long chain n-paraffins (C36, C32, and C28) and their mixtures obtained from melt or solutions in decane give well-resolved low angle spectra in the absence of poly(ethylene butane)s (PEB). Added PEB, which disrupt gel formation and improve significantly the fluidity of paraffins solutions in decane, have the effect of disrupt lamellae layering as observed by XRD since the PEB co-crystallizes with the paraffin and the non-crystallizable side ethyl chains in PEB would provide a steric barrier against platelet stacking. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
