Thermoanalytical evaluation of the oxidative stability of liquid polybutadienes
Kovářová, Jana ; Podešva, Jiří
Hydroxy-terminated liquid polybutadienes, as commercially available polymeric diols, are used in teh production of special types of elastomeric polyurethanes. A comparison of the oxidation susceptibility in a series of hydroxy-terminated polybutadiene rubbers in relation to the degree of hydrogenation shows that the oxidative stability of liquid rubbers gradually increases with the decreasing content of double bonds in the 1-PB chains.
Phase equilibrium in aqueous solutions of octablock copolymer of poly(propylene oxide)/poly(ethylene oxide)
Sikora, Antonín ; Pleštil, Josef ; Kratochvíl, Jaroslav
The phase diagram of the associating octablock star copolymer of polyethylene oxide/polypropylene oxide in water was constructed on the basis of visual observations and DSC measurements.
DSC study of blends of two crystallizable polymers
Kratochvíl, Jaroslav ; Sikora, Antonín
DSC studies have shown that the blend of polycarbonate/polyoxyethylane shows partial miscibility in amorphous phase at temperatures close to Tm POE. At temperatures close to TmPC polymers do not interact. Crystallization of PC is stimulated and that of POE retarded by presence of the other polymer in the blend.
Study of poly(ethylene oxide) melting by temperature-modulated DSC
Sikora, Antonín ; Dolgoshey, V. B. ; Baldrian, Josef ; Kratochvíl, Jaroslav
Result of temperature-modulated DSC study of poly(ethyleneglycol) with molecular weight 3000.
Kinetics of nonisothermal crystallization of polymers
Kratochvíl, Jaroslav ; Sikora, Antonín
Nonisothermal crystallization of poly(N-methyldodecanol lactame) was studied by DSC with cooling rate 2-40 k/min.
