Suspension polymerization molecular weight measurements

Enzymatic degradation is mainly evaluated by means of (1) weight loss of polymeric materials, (2) optical density of polymer suspensions, (3) titration of water-soluble materials, (4) molecular weight measurement, (5) physical property... [Pg.384]

The rate of polymerization was determined from the amount of polymer obtained per unit of time. The productivity of the metallocene catalyst was calculated from the quantity of polymer and the catalyst metal fed into the reactor. The resulting polymers were investigated by gel permeation chromatography (GPC) to determine the molecular weight distribution together with the average molecular weights. The density was measured on pressed films by means of the suspension method in a mixture of water and isopropanol. 13C-NMR-spectroscopy was applied to analyze the composition of copolymers and to evaluate their structure. [Pg.74]
