Coarsening in the two-dimensional soap froth and the large-Q Potts model: A detailed comparison

Abstract: A detailed comparison between the experimental evolution of a two-dimensional soap froth and a next-nearest-neighbour Q = ∞ Potts model on a square lattice starting from identical initial conditions is presented. We compare the pattern evolution, dynamics, distribution functions and correlations of the two systems. We also examine in detail the relation between number or sides and area (Lewis' law) and two measures of pattern disorder. Overall agreement is found between the model and simulation, with a few systematic deviations which suggest that side redistribution is affected by subtle anisotropy and equilibration effects.

Elastic fibers and articles made therefrom, including crystalline and crystallizable polymers of propylene

Abstract: Improved thermoplastic polymer soft elastic fiber blend compositions including a crystalline isotactic polypropylene component and a crystallizable alpha-olefin and propylene copolymer component, the copolymer comprising crystallizable alpha-olefin sequences. In a preferred embodiment, improved thermoplastic polymer blends are provided prepared from 0% to 95%, preferably 2% to 40% of the crystalline isotactic polypropylene and from 5% to 100%, preferably 60% to 98% of a crystallizable ethylene and propylene copolymer, wherein said copolymer comprises isotactically crystallizable propylene sequences and is predominately propylene. The resultant blends manifest unexpected compatibility characteristics, increased tensile strength, and, improved resistance to elastic deformation.
