Method of testing polymer monofilaments for compressive deformability in the radial direction

A method and an apparatus for testing polymer monofilaments in short-time and long-time compressive creep in the radial direction are proposed. By this means it is possible to test five specimens simultaneously with indenters of selected shape at a constant givenload.I. M. Gubkin Moscow Institute of the Petrochemical and Gas Industry.

Reaction of alkylmercury and alkyltin compounds with diphenylmethyl salts

Conclusion The composition of the products of the reaction of peralkylmercury and perlalkyltin compounds with diphenylmethyl fluoborate depends on the presence and nature of a hydrogen in the alkyl radical. In the absence of a hydrogen, substitution (dealkylation) occurs to form alkyldiphenylmethane; in its presence, elimination and substitution take place.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1382–1386, June, 1982.
