On the basis of these results, we deduced that the residual alkoxide was not active enough to initiate propylene oxide polymerization in the near end of the polymerization. Therefore, there might have been another factor that limited the increase of the relative molar mass of poly(propylene oxide...

wherex(g/mol) is the molar mass of the starting metal, 100% is the weight of the starting metal, 16 (g/mol) is the molecular weight or molar mass of oxygen, andy% is the weight gained by heating. For example, let us say we are starting with 100% of metal. That corresponds to ...
Thermodynamics of micelle formation by polystyrene-block-poly(ethylene/propylene) in n-octane and 5-methylhexan-2-one The influence of the molar mass and chemical composition of copolymers on the thermodynamics of the micellization process has been investigated using two p... José,R.,Quintana,.....
The reaction kinetics, mass transfer and solubility of carbon dioxide in a single or mixed aqueous solution of piperazine have been studied by various researchers [2], [3], [4], [5], [6], [7], [8], [9], [10]. Kadiwala et al. [8] concluded that piperazine had a capacity for...
The phase behaviour of low molar mass poly(ethylene-alt-propylene) -poly(dimethylsiloxane) (PEP-PDMS) is investigated in this thesis by the combination of dynamical mechanical spectroscopy (rheology) to measure phase transition temperatures, and small-angle x-ray scattering to identify the morphology...
