Patent number: 6429166Abstract: Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an inert organic compound, mixing the resulting slurry with the initiator and stripping off the inert organic compound. Using this method, an active alkylene oxide polymerization catalyst is prepared. It is not necessary to use a separate organic complexing agent in the preparation.Type: GrantFiled: May 19, 2000Date of Patent: August 6, 2002Assignee: Dow Global Technologies Inc.Inventor: Richard M.

Patent number: 6429281Abstract: In accordance with the present invention there are provided cycloaliphatic epoxy compounds and thermosetting resin compositions prepared therefrom. Inventive compounds are based on polycyclic hydrocarbon backbones, as illustrated by the following exemplary structure: wherein: each R is independently lower alkyl or halogen, n′″ is 1 up to about 8, and each x is independently 0, 1, or 2. Inventive compounds provide resins with desirable characteristics such as, for example, hydrophobicity, high Tg values, ionic purity, hydrolytic stability, and the like.Type: GrantFiled: July 1, 1999Date of Patent: August 6, 2002Assignee: LoctiteInventors: Stephen M.

Publication number: 20020099168Abstract: In accordance with present invention there are provided novel epoxy derivatives of polycyclic compounds. Invention epoxies are particularly suited for incorporation into thermosetting resins. Resins comprising invention epoxies are hydrophobic and therefore less susceptible to popcorning upon cure or use in high temperature applications. The hydrophobicity also makes such resins less susceptible to hydrolysis upon exposure to moisture.Type: ApplicationFiled: December 18, 2001Publication date: July 25, 2002Applicant: LoctiteInventors: Stephen M.

Patent number: 6388048Abstract: Metal [hexacyanocobaltate, cobalthexanitrite nitroferricyanide] complexes are useful alkylene oxide polymerization catalysts. The metal is any that forms a precipitate with the hexacyanocobaltate, cobalthexanitrite and nitroferricyanide groups. These catalysts are made from less expensive raw materials than the common zinc hexacyanocobaltate catalysts, and provide short induction periods and many cases more controlled exotherms. In addition, the metal [hexacyanocobaltate, cobalthexanitrite nitroferricyanide] catalysts often provide poly(propylene oxide) polymers having very low unsaturations, even when the catalyst is complexed with a complexing agent such as glyme.Type: GrantFiled: May 19, 2000Date of Patent: May 14, 2002Assignee: The Dow Chemical CompanyInventors: David E.
