The polymers, which combine the structures of silicones and polyaromatics, possessed high thermal stabilities and were obtained as materials which ( 1 ) failed to melt or soften at 350°C., ( 2 ) were gumlike at elevated temperatures, or ( 3 ) were soluble, film- and fiber-forming ...
Two distinct MgO NPs were prepared by changing the amount of acacia gum and termed as AGM-10 and AGM-20. Adsorption experiment cleared that both NPs efficiently removed the selected metallic species. The removal trend for AGM-10 followed Ni(II)> Pb(II)> Cd(II)> Cu(II)> Zn(II)> Co(...
Tara gum has been considered as a possible replacement for carob gum in the formation of kappa carrageenan-galactomannan mixed gels. The mechanical properties of tara-carrageenan mixed gels have been measured and compared with the mechanical properties of carob-carrageenan mixed gels.doi:10.1002/chin....
It was then filtered and the solvent was evaporated to give 30 as a viscous gum which was pure enough to further use. THREONINEDITHIANE 33 (SEE SCHEME 7). Pentyldithiane 32 (Hirai, Heterocyles 1990, 30(2, Spec. Issue), 1101) (200 mg, 0.97 mmol) was dissolved in 10 mL of CH2Cl2 ...
