Thermal and dynamic mechanical analysis of cross-linked poly(esterurethanes)
PublicationW pracy przedstawiono wyniki badań termograwimetrycznych oraz termomechanicznych usieciowanch za pomocą styrenu i metakrylanu metylu poli(estrouretanów). Uzyskane wyniki pozwoliły stwierdzić, że stabilność termiczna poli(estrouretanów) jest wystarczająca do wielu zastosowań technicznych. Przeprowadzone analizy wykazały również, iż polimery sieciowane styrenem wykazują separację fazową.

Thermal decomposition of some aromatic azomonoethers. Part II. Non-isothermal study of three liquid crystals in dynamic air atmosphere
PublicationW ramach pracy zweryfikowano stabilność termiczną trzech barwników azowych o właściwościach ciekłokrystalicznych - potencjalnych prekursorów do otrzymywania warstw stosowanych w optyce nieliniowej. Zarejestrowano przebiegi TG, DTG, DTA oraz DSC jak również analizowano skład gazów powstających podczas rozpadu za pomocą przystawki FTIR. Przeprowadzono analizę kinetyki rozkładu, wyznaczając energię aktywacji procesu.

Synthesis, structure and properties of poly(ether-urethane)s synthesized using a tri-functional oxypropylated glycerol as a polyol
PublicationThe main aim of this work was to obtain poly(ether-urethane)s using tri-functional polyoxyalkylene polyol (Rokopol G1000), which introducing the chemical cross-links into the structure of polyurethanes. Poly(ether-urethane)s were prepared using two-step method, called prepolymer method, which involves in the first step the reaction of 4,4'-diphenylmethane diisocyanate (MDI) and tri-functional polypropylene glycol glycerol triether...

Synthesis and thermal studies of flexible polyurethane nanocomposite foams obtained using nanoclay modified with flame retardant compound
PublicationThis work presents thermal studies of nanocomposites based on the flexible polyurethane (PU) matrix and filled using montmorillonite organically modified with organophosphorus flame retardant compound. Flexible PU nanocomposite foams were prepared in the reaction carried out between reactive alcoholic hydroxyl and isocyanate groups with the ratio of NCO to OH groups equal to 1.05. The amount of an organoclay ranging from 3 to 9...

Cadmium complex possessing simultaneously silanethiolato- and dithiocarbamato-ligands. A novel single-source precursor of cadmium sulfide
PublicationThermal decomposition of suitable coordination compounds may be used as efficient route for fabrication of semiconducting layers. A new potential CdS precursor—a cadmium complex with all-sulfur Cd-coordination sphere [Cd{l-SSi(OBut)3}(S2CNC4H8)]2 (1) —has been prepared and its properties are investigated. The complex was obtained in the reaction between dimeric bis(tri-tert-butoxysilanethiolato) cadmium(II) [Cd{SSi(OBut)3}2]2 and...
