  • Patent number: 6359147
    Abstract: Reactions of ring systems, such as aziridines, oxetanes and oxiranes with carboxylic acids, anhydrides, imides, lactones and carbonate esters are catalyzed by C3-C60, substituted or unsubstituted, straight or branched-chained, alkyl, aryl, or aralkyl carboxylate Cr+3 salts, preferably chromium +3 octoate. The catalysts also accelerate the reaction of hydroxy compounds with anhydrides, and of thiiranes with anhydrides. The catalysts selectively enhance the conversion of ring systems to form monomers, prepolymers, copolymers, functional end-group monomers, functional end-group prepolymers, and functional end-group polymers rather than forming homopolymers. By varying the catalyst concentration, molar ratios, and reaction temperatures, the reaction time required to form the desired product can be controlled.

  • Patent number: 6359014
    Abstract: The present invention comprises preparations of polyoxypropylene/polyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. Because the preparations of polyoxypropylene/polyoxyethylene copolymers which comprise the present invention are a less polydisperse population of molecules than the prior art polyoxypropylene/polyoxyethylene copolymers, the biological activity of the copolymers is better defined and more predictable.
