    Notes: Abstract Structure-activity relationship (SAR) observations were made for theZ-type European corn borer moth pheromone, (Z)-11-tetradecen-1-ol acetate, and a series of analogs with fluorination in the alcohol portion of the molecule. The attractiveness of these analogs and the pheromone was compared to the electrostatic potential map of the molecular mechanics (MM) minimized lowest energy conformation for each compound. A critical range of electrostatic potential on the protons of the double-bond appears to be essential for optimal acceptor fit and attractiveness.

    Description / Table of Contents: Plastographic Material- und Failure Analysis of Polymer ComponentsOptical light microscopic- and SEM-investigations and EDX-analysis are carried out, to examine the material and to documend the microstructure of polymers using polished or thinned section techniques. Additionally microhardness- and DSC-testings are used. Deficiencies of manufacturing of glass-fiber-reinforced plastics and polypropylene are described as well as failures due to the processing media of components.
    Notes: Licht- und rasterelektronenmikroskopische Untersuchungen, energiedispersive Röntgenmikroanalysen an Anschliffen und Dünnschliffen sowie Mikrohärte- und DSC-Messungen ermöglichen die Gefügedarstellung und Werkstoffbeurteilung an Polymerwerkstoffen. Herstellungs- und Fertigungsfehler sowie Schädigungen durch Betriebsmedien an Bauteilen aus glasfaserverstärkten Kunststoffen (GFK) und Polypropylen werden dargestellt.
