n (Mn) The sum of the molecular weights of all the individual molecules in a given polymer sample divided by the total number of molecules. The defining equation is$$M_n = \\sum {n_i} M_i/\\sum {n_i = }doi:10.1007/978-1-4419-6247-8_8026Jan W. Gooch...
athe number average molecular weight (Mn) was determined by gel permeation chromatography (GPC) using commercially available PECH and polystyrene standards as reference in THF. 数字平均分子量(Mn)在THF取决于胶凝体渗透过程色谱法(GPC)使用买得到的PECH和多苯乙烯标准作为参考。[translate]...

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 ...
A polyester resin has a molecular weight distribution (MWD) of approximately from 1.0 to 2.2, wherein molecular weight distribution (MWD) is a weight-averaged molecular weight (Mw)/a number-averaged molecular weight (Mn); and a luminosity (L*) of from ap
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...
but also to different experimental procedures or varying assay conditions, such as temperature and pH value. When comparing a single measurement to the geometric mean of all other measurements for the same enzyme-reaction pair, we found an average deviation of 3.3-fold (mean deviation on\({\log...
