    摘要: Partially alkylated polyamines which may be viewed as low molecular weight polymers of x-amino-y-methylenephenyl are effective curing agents in combination with other polyamines and polyols in reaction injection molding for diverse class of polyisocyanates. Alkylation may range from 5 up to 100 percent to afford polyamines with a board spectrum of cure times, as well as to give elastomers with an interesting and useful diversity of properties. Such polyamines may be used as a constituent in a blend of polyamines as the isocyanate-reactive component, in which case the elastomer may be viewed as predominantly a polyurea, or as a constituent in a blend with polyols, in which case the elastomer may be viewed as an elastomer with both urethane and urea segments.

    摘要: N,N'-dialkyl- and diaylphenylenediamines are effective curing agents in combination with other polyamines and polyols in reaction injection molding for a diverse class of polyisocyanates. The diamines provide a broad spectrum of cure times, as well as giving elastomers an interesting and useful diversity of properties. Such polyamines may be used as a constituent in a blend of polyamines as the isocyanate-reactive component, in which case the elastomer may be viewed as predominantly a polyurea, or as a constituent in a blend with polyols, in which case the elastomer may be viewed as an elastomer with both urethane and urea segments.

    摘要: Largely alkylated polyamines which may be viewed as low molecular weight polymers of x-amino-y-methylenephenyl are effective curing agents for a diverse class of urethane prepolymers. The resulting polyurethanes are thermosetting polymers with excellent compression set and tensile strength. Because the properties of the resulting polyurethane vary only slightly near the optimum stoichiometry of curing agent-prepolymer, the use of the curing agents of this invention presents the advantage of being very tolerant of operator mixing error.

    摘要: The polyureas resulting from curing polyfunctional isocyanates having at least three isocyanate groups with a N,N'-dialkylmethylenedianiline are broadly useful as coatings on the surface of objects made of metal, wood, glass, or plastic. The diamine N,N'-di(2-butyl)4,4'-methylenedianiline is a particularly useful diamine. Biurets are an especially desirable class of polyisocyanates for the polyureas of this invention, particularly those arising from polymethylene diisocyanates and aromatic diisocyanates.

    摘要: The polyurea resulting from curing polyfunctional isocyanates having at least three groups with a N,N'-dialkylmethylenedianiline are broadly useful as coatings on the surface of objects made of metal, wood, glass, or plastic. Such coatings may be made based on either a 1-pack system or 2-pack system. The diamine N,N'-di(2-butyl)4,4'-methylenedianiline is a particularly useful diamine. Biurets are an especially desirable class of polyisocyanates for the polyureas of this invention.
