    Notes: A mathematical model of the basic polymerization kinetic scheme, that involves only initiation, propagation, and termination reactions, has been developed. It was assumed that the propagation and termination rate constants are independent of the chain length. It has been shown that the model predicts the effect of autoacceleration on the formation of the insoluble polymer component. In order to demonstrate the applicability of the mathematical model for description of dispersion radical polymerization, the evolution of the size distribution of growing polystyrene particles has been measured with the Flying Light-Scattering Indicatrix method. © 1997 John Wiley & Sons, Inc.

    Notes: Summary The possibility of employing a number of adsorbents (polyphenylquinoxaline, Tenax GC, Carbopak C, graphitized thermal carbon black, silica gels modified with pyrocarbon or hexamethyldisilazane) for the trapping of organic traces from air has been investigated. Adsorption capacities of these adsorbents with respect to a number of volatiles released from certain plastics used as building material (polyvinylchloride, Relin, Acronal, etc.) have been measured. A number of the volatiles were identified by gas chromatography — mass-spectrometry after trapping on the adsorbents investigated. Chromatographic separation after trapping on the adsorbents was carried out on wall-coated open-tubular capillary columns as well as in capillary columns packed with graphitized thermal carbon black.
