Crystal structure of H-ShapedAlkane H 3C(CH 2) 2} 2OHC(CH 2) 4COH{(CH 2) 2CH 3} 2 and its compatibility with high density polyethylene

We synthesized a complex branched alkane (H-shaped) with two hydroxyl groups attached to branching points and studied its crystalline structure and also compatibility with high density polyethylene (PE). Results of DSC and X-ray diffraction on solution-crystallized and bulk-crystallized H-shaped alkanes gave same lattice constants for a triclinic type of crystal, a = 1.04nm, b = 1.27nm, c = 1.60nm, α = 95.7°, β = 91.6°, and γ = 109.4°. H-shaped/PE binary system showed a solid solution region 0.05 H H is the volume fraction of H-shaped alkane. On the other hand, in the region 0.46 H
