Relation between deformation and rotational isomerism

Autor: I.I. Novak, P.M. Pakhomov, M. V. Shablygin, V. E. Korsukov

Publikováno v: Polymer Mechanics. 11:919-922

In uniaxially oriented polyethylene and polyethylene terephthalate films conformational transitions were studied by the absorption IR-spectroscopy method during deformation of the specimens carried to rupture in a wide range of temperatures and with

Variation of the conformational spectrum during elongation of flexible polymers

Autor: Ye.S. Tsobkallo, P.M. Pakhomov, I.I. Novak, V.Ye. Korsukov

Publikováno v: Polymer Science U.S.S.R.. 20:18-24

The variation in concentration and orientation of various rotational isomers during orientational drawing of polyethylene (PE) and poly(ethylene terephthalate) (PETP), is followed by means of infrared spectroscopic analysis. It is shown that the bala

Relation between mechanical properties and conformational composition of polymers

Autor: V.Ye. Korsukov, P.M. Pakhomov, M. V. Shablygin, I.I. Novak

Publikováno v: Polymer Science U.S.S.R.. 26:1441-1447

A study was made of physico-mechanical properties of a number of synthetic fibres, according to the conformational composition of the polymer. As a result of experimental investigations it was shown that conformational composition is of decisive impo

Influence of intermolecular interaction on kinetics of conformational transitions in poly-m-phenyleneisophthalamide

Autor: P.M. Pakhomov, M. V. Shablygin, V. E. Korsukov, I.I. Novak

Publikováno v: Journal of Applied Spectroscopy. 43:891-895

The authors study the kinetics of conformational transitions during crystallization from a glasslike state and they compare the results obtained with the character of the conformational transitions in other polymers with a lower IMI energy. As the in

Investigation of the rupturing of polyethylene films reinforced with grafted polystyrene

Autor: A.I. Kurilenko, V.Ye. Korsukov, A.A. Shunkevich, I.I. Novak

Publikováno v: Polymer Science U.S.S.R.. 17:2598-2604

IR spectroscopy is used in a kinetic study of the accumulation of ends of broken PE macromolecules in loaded PE films reinforced with grafted discrete polystyrene structures. The rate of mechano-chemical degradation of PE in the graft films is consid

Methods of investigation measurement of concentration of products of decomposition on the surface of polymer films

Autor: I.I. Novak, V. I. Vettegren, A. Chmel

Publikováno v: Polymer Science U.S.S.R.. 15:2154-2159

From IR spectra obtained by transmission and by complete irregular internal reflection concentrations were determined of products of decomposition formed polyethylene and polypropylene films during preparation from melt. It was found that the proport
