“…A somewhat similar initial plateau, termed a “resting period,” was observed by Jellinek and Northey [10] for the adsorption on charcoal of polystyrene from methyl ethyl ketone containing small quantities of water. Thorough drying of the solvent eliminated the resting period and decreased the rate of adsorption.…”

The rate of adsorption of polystyrene from cyclohexane solu tion on chrome felTo ty pe plates ",as studi ed for a concentration range of 10-1 to 10-4 mg!m l. 1'\\' 0 molec ular weight fraction s of p oly mers, 76,000 and 38, 100, were prepared by t h e anionic poly m erization of sty re ne tagged with t ritium , and a radiotracer technique was used t o m easure directly the a moun t of polyme r adsorb ed on t h e surface. The rate of adsorption is very d ep endent on t he cOllecntration of t h e poly mer solution, a nd t imes vary ing from minutes to sever al hours wcre r equ ired before maximum adsorption occurred for th e concen t ration ra nge studied. Th e ra te of d esorption is strongly dependent on t he adsorbance; it was hypo t hes ized that t his is d ue to t he number of attachme nts per molec ule also va ry in g with adsorbance. The conformatio n of the adso rbrd molecule as indicated by these res ults a nd those determined by t he measurement of th e thickncss of the adso rbed laycr by ellipsometr y is disc ussed.

Das Adsorptionsverhalten anorganischer Oxide, insbesondere TiO2, in Polyesterlösungen wird untersucht. Die Adsorptionssättigungswerte stehen mit den spezifischen Oberflächen und der chemischen Wertigkeit der Adsorbenten in direktem Zusammenhang. Die Adsorption ist, besonders für niedere Molekulargewichte, von den Endgruppen der Polyesterketten abhängig. Polyestermoleküle mit Carboxylendgruppen adsorbieren um den Faktor 6–8 stärker als Polyester mit veresterten Endgruppen. Die Adsorption nimmt bei Polyestern mit Carboxylendgruppen mit fallendem Molekulargewicht zu. Abnehmende Polarität der Polyestermoleküle bewirkt eine Zunahme der Adsorption. Diese Erscheinung findet eine Erklärung darin, daß zur Bindung der Molekülketten an die Pigmentoberfläche allein die Estergruppen beitragen. Der Einfluß der Wechselwirkung Polyester‐Lösungsmittel auf die Adsorption wird mit Hilfe der Viskositätszahl und der Hugginsschen Konstanten untersucht. Die experimentell bestimmten Adsorptionsmengen werden mit den nach verschiedenen Modellen der adsorbierten Schicht berechneten Mengen verglichen. Es ergibt sich, daß die Mehrzahl der Polyester in Form von Schlaufen adsorbiert wird.
