Notes: Abstract The most effective lure for maleAmorbia cuneana (Walsingham) in Orange, Ventura, and Riverside counties of California was previously found to be a 1∶1 ratio of (E,E)-10,12- and (E,Z)-10,12-tetradecadien-1-ol acetates. In subsequent field tests in San Diego and Santa Barbara counties, this lure was ineffective. Analysis of sex pheromone glands (SPG) of femaleA. cuneana from these two counties showed theEE:EZ ratio to be about 1∶9 and synthetic lures of this composition were highly attractive in these areas. Analysis of the SPG of a number of females from both areas showed that there were three population types: two in the low ratio areas possessed 37 and 58%EZ, and the third in the high ratio areas possessed 89%EZ.

Description / Table of Contents: Durch die Synthese von cyclischen Acrylaten wurde eine Reihe von Monomeren erhalten, die hohe Reaktivitäten der Copolymerisation bei gleichzeitiger Fähigkeit zur radikalischen Ringöffnungspolymerisation aufweisen. Sie wurden polymerisiert, um einen Pyruvatester in die Polymerkette einzuführen. Eine Reihe von Spiromethylencyclohexadienen wurde hergestellt, um neben der Carbonylgruppe und gespannten Ringen weitere Gruppen zu finden, die die radikalische Ringöffnungspolymerisation fördern. Bei ihrer Polymerisation wurden Polymere mit einer p-Phenylengruppe in der Kette erhalten.

Notes: In order to find a series of monomers with high reactivities in copolymerization and still undergo free radical ringopening polymerization, a series of cyclic acrylates were synthesized and polymerized to insert a pyruvate ester into the backbone of the polymer. In order to discover groups other than the carbonyl groups and strained rings that would promote free radical ring-opening polymerization, a series of spiro methylenecyclohexadienes were prepared and polymerized to give a polymer with a p-phenylene group in the backbone.
