Abstract
Statistically valid equations correlating properties of ethylene and propylene oxides block copolymers of Pluronic type with molecular mass of polyoxybutylene chain, the content of ethylene oxide and concentration are given. The following properties are considered: density, viscosity, melting point, cloud point, surface and interfacial tension, foaming, wetting and washing ability.

For -rhombohedral boron and boron carbide, the hitherto best-investigated icoasahedral boron-rich solids, the concentrations of structural defects and electronic gap states are quantitatively correlated. In this way the theoretically determined valence electron de5ciencies are exactly compensated, a
