    摘要: The biocidal activity of N-(2-methyl-1-naphthyl)-maleimide is vastly improved by chelating it with an amine wherein each free hydrogen on each amino group has been replaced by the groups --(CH.sub.2).sub.n COOY wherein n represents 1 or 2 and each Y represents hydrogen, ammonium or an alkali metal cation.

    摘要: Disclosed is a synergistic catalytic combination of 1,2-dimethylimidazole with tris(3-dimethylaminopropyl)amine and a salt of 1,8-diazabicyclo(5,4,0)undecene-7. The combination catalyst is useful in polyurethane systems such as elastomers, microcellular, rigid, semirigid, and flexible foams, such as integral skin semiflexible foams used in the manufacture of steering wheels.

    摘要: Polyurethanes based on a resole-type polyol can be significantly improved in their friability when the urethane catalyst is a fully neutralized tertiary amine salt and butyl benzyl phthalate is used as the plasticizer.The polyol is prepared by reacting a phenol and formaldehyde under substantially anhydrous conditions with continuous removal of water, and has a water content of no more than about 5%.
