Results of experimental and theoretical studies on gas selective properties of polyvinyltrimethylsilane (PVTMS) under bombardment with 50–150 keV C + and Ar + ions with doses of 5×10 14 −10 16 cm −2 are presented. It was found that permeabilit

Strong intermolecular interactions in crystalline 3-(4′butyl)- and (4−heptylphenyl)-7-propoxycoumarins, resulting in layered packing, prevent the formation of associates with high anisotropy of intermolecular interaction energy (IIE), so that on

1. The structure of the isocyanate functional group in organic isocyanates in the crystalline state is analogous to that in the gas phase. 2. The isocyanate group (H)C1-N=C2=O exists in a trans conformation in all three of the isocyanates studied. 3.

We have studied the gas-separation properties of industrial polyvinyltrimethylsilane (PVTMS) membranes, as well as of experimental specimens of polyarylate siloxane, modified with ions C+, Ar+, B+, and N+.

A planar structure for molecules of 2-(2′-methylaminophenyl)-4H-3,1-benzoxazine-4-one was found by x-ray structural analysis. Shortening of the N-Ph bond and lengthening of the distance between amino- and azine-N atoms in comparison to the tosyl an

1. In urethane crystals, infinite chains of hydrogen bonds organize the urethane molecules into layers with two principal types of packing: “fir-tree” and “stacked.” The stacked packing sometimes leads to the formation of a quasiskeletal stru
