Diene elastomer containing vinylaromatic monomer units; number-average molecular weight Mn of less than 2000 g/mol; glass transition temperature Tg of greater than -25 degrees C.; improved wear resistance; passenger-vehicle tires.doi:US7329704 B2...
The present work deals with changes in the number average molecular weight (Mn) of PTFE irradiated at different temperatures. A decrease in Mn was observed and attributed to the scission of polymer chains. On the other hand, it was also observed that Mn decreased to a minimum value with ...
From the definition of the number average molecular (Mn(c)) weight one has cM1/Mn(c) = M1 Σ i = 1 n ci/Mi; it is shown that this may also be obtained from the relation cM1/Mn(c) = ∫0cM1/MW(C)dc, where Mw(c) is the weight average molecular weight. For nonideal solutions...

It is necessary to correct the number-average molecular-weight ( Mn) values of organic compounds obtained by colligative methods such as vapour-pressure osmometry (VPO) for dissociation of any acidic functional groups present. A novel correction method for the determination of Mn corr-values is ...
This method permits to determine the molecular weight distribution and the average molecular weights (Mn, Mw). GPC is a special type of liquid chromatography in which the sample is separated according to the hydrodynamic volumes of the individual constituents.According to their size, the eluted ...
