“…The continuous distribution of particle sizes of polystyrene latex was measured by intensity correlation spectroscopy (77). The technique combining zonal ultracentrifugation and angular light scattering was developed for size distribution analysis of polydisperse and chemically mixed polymer latex systems (203). Low angle laser light scattering provides a measure for the degree of nonrandomness in cross-linking.…”

Die Bestimmung der GroBe von PVC-Latexteilchen mit mittleren Teilchendurchmessern kleiner 40 nm gelingt durch Ultrazentrifugation mit schlierenoptischer Detektion. Bimodale Latices rnit Verteilungsmaxima oberhalb und unterhalb 40 nm konnen durch Ultrazentrifugation und getrennte Detektion mittels Triibungsmessung und Schlierenoptik charakterisiert werden. Ultrazentrifugation, Elektronenmikroskopie, Lichtstreuung und Trubungsmessung fuhren bei monomodalen Latices fur vergleichbare Mittelwerte zu gleichen mittleren Teilchendurchmessern. onpeaeJcenuu pacnpeaefienw uacmuy no p a m e p a 4 y nofiusunufimopudnux JcameiicosYJIbTpaqeHTPH~yrUpOB~EIeM OlIpeAeJIHJIklCb pa3MepbI IIOJIHBHHHJIXJIOPHAHMX JIaTeHCHbIX raCTEiq.

Bimodal distributions having maxima above and below 40 nm can be characterized by ultracentrifugation and seperate detection by turbidimetric and strioscopic methods. Ultracentrifugation, electron microscopy, light scattering and turbidimetry provide comparable particle diameters of monomodal latices for corresponding average values.
