Zimm plot Type of double extrapolation used to determine the weight-average molecular weight in light-scattering photometry. [Pg.80]

The amount of excess light scattered by dilute polymer solutions compared with that scattered by the pure solvent is used routinely to determine the weight average molecular weight of polymers, A/, ... [Pg.53]

ASTM D 4001-93, Test Method for Determination of Weight-Average Molecular Weight of Polymers by Light Scattering, ASTM, West Conshohocken, Pennsylvania, 1997. [Pg.162]

Low Angle Laser Light Scattering Photometry. Weight-average molecular weights were determined with a KMX-6 photometer (LDC/Milton Roy). The light source was a 2 mW vertically polarized helium-neon laser (A =... [Pg.149]

A Chromatix low-angle light scattering G.P.C. detector was also employed for the determination of the weight average molecular weight (Mw), as well as a sensitive detector, in order to assay absolutely the Mw versus elution volume profile for a series of star-branched polyisoprenes and polybutadienes. The results indicate that under optimum conditions a relatively well defined number of arms can be achieved with DVB linking. [Pg.557]

The weight average molecular weight(Mw) measurements were determined by utilizing the Chromatix low angle laser light scattering G.P.C. detector (14). The G.P.C. column set was similar to those mentioned above and the carrier solvent was tetrahydrofuran at 25°C with a flow rate of 1.5 ml/min. The (dn/dc) values of both polybutadiene and polyisoprene were determined in THF with the Chromatix KMX-16 differential refractometer. [Pg.561]
