aWe all be happy, regardless of each other's happiness 我们全部是愉快的,不管彼此的幸福[translate] 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...
Molecular Weight (Polymers) refers to the sum of the atomic weights of individual atoms in a polymer molecule, indicating the average length of the polymer chains in the bulk resin. It can be calculated using number average molecular weight (Mn) or weight average molecular weight (Mw). ...
The relationship between the molecular weight of the polymers and the amount of 4-methoxyphenol used was consistent with anionic polymerization, of which the molecular weight is known to be inversely related to the amount of the initiator. When the number-average molecular weight ( Mn ) is in ...
EXPERIMENTAL PROCEDURES Samples d-PE with a weight average molecular weight of Mw = 600 000 and molecular weight distribution of Mw/Mn = 2 and h-PE with various molecular weights of Mw = 58 000, 300 000 and 2 000 000 and Mw/Mn = 8 ~ 12 were used in this experiment. The blends ...
