In this article, we describe the synthesis of polyretherketones (PEK) by the method of acceptor-catalytic polycondensation, using oligoketones with different condensation degree (n = 1, 10, 20), isophthalic and terephthalic acid dichloride hydrides and 2,2-di-(4-hydroxyphenyl)propane. Their properties were also studied

An experimental breadboard model of such processor based on the multichannel acoustooptical modulator intended for processing ofradar signals is described, results ofmathematical simulation and experimental investigations are presented.
A comparative analysis of the basic physical and chemical properties of non stabilized polyalkyleneterephthalates and their compositions with polymers containing oximates groups is submitted. It is shown that the use of new polyformaloximates (PFO) and polyarylateoximates (PAO) as modifying additives allows improving the operational properties and technical characteristics of polyalkylenetherephthalate compositions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
