The molecular weight distribution (MWD) was examined by gel permeation chromatography (GPC) on three samples of styrene oligomers prepared by anionic oligomerization, each of which had averaged degree of polymerization less than ten. Accurate information for MWD could be easily obtained, when a GPC ...
The molecular weight (MW) and molecular weight distribution (MWD) of the product polymer can be effectively controlled by the feed ratio of monomer to initiator. This paper preaeats a study on the MWD of styrene polymerization in a SFR. The MWD model parameters are regressed with experimeatvJ...

molecular weight,weight of amoleculeof a substance expressed inatomic mass units(amu). The molecular weight may be calculated from the molecularformulaof the substance; it is the sum of theatomic weightsof the atoms making up the molecule. For example, water has the molecular formula H2O, indi...
The molecular weights of nine fractionated samples of butadiene-styrene copolymer were determined osmometrically in toluene at 25°. Experimental technique for the use of osmometer and the swelling of cellophane membrane in 5—30 pct NaOH solutions have been described. The change of permeability durin...

Molecular weight distributions in styrene polymerization with asymmetric bifunctional initiators We model the molecular weight distribution (MWD) of polystyrene obtained using asymmetric bifunctional initiators. We do that by extending an existing mode... M Asteasuain,A Brandolin,C Sarmoria - 《Polymer...
Hollow poly(alpha-methylstyrene) (PAMS) shows application in inertial confinement fusion experiments as the degradable mandrels of glow plasma polymer shells. However, the molecular weight of PAMS has great influence on the quality of mandrels. In this work, this influence was systematically studied...
