The creation of surfactants of a new type is discussed on the basis of their synthesis and properties. These are the bi-anchored compounds having 2 ionic groups bound to a flexible non-polar chain and are cation-active oligourethanes. The high surfac

An investigation has been made of ionometric polyurethanesemicarbazides containing quaternary halide (Cl, Br, I) pyridinium salts, used as chain elongators of the rigid blocks. It has been shown by use of a number of methods (low-angle X-ray diffract

The photochemical reaction of sulphur dioxide with PE under irradiation with light of λ = 313 nm has been studied. The kinetic results indicate an absorption reaction mechanism. It is shown that “exiplexes” of sulphur dioxide with the PE molecul

The influence of the method of synthesis on the structure and properties of cation-active polyurethane semicarbazides has been studied. It was shown that in polyurethane ionomers, prepared by a single stage method, the character and nature of structu

A study has been made of the photopolymerization kinetics of methyl methacrylate in bulk. There is an induction period if λ>310 nm, but this is reduced by previous evacuation of the vessels at 300‡ C and by exposure to shortwave UV. Wavelengths ou

ONE of the most effective methods of modifying polyethylene (PE) for the pur: pose of increasing its heat resistance, its resistance to organic solvents, and other technically valuable properties is to subject it to radiation crosslinking [1]. I t ha
