    摘要: Alkoxysilyl-terminated prepolymers in which the alkoxysilyl group is linked to a tertiary nitrogen group through a Cl carbon spacer exhibit excellent moisture curing reactivity and yet are easily prepared. The tertiary nitrogen group-containing α-aminoalkoxysilyl group is introduced into the prepolymer by reacting a tertiary nitrogen group-containing α-aminoalkoxysilane with an isocyanate-terminated prepolymer or isocyanate-functional precursor thereof.

    摘要: Particles of metal and non-metal oxides may be readily functionalized with organosilyl groups, even in the absence of catalysts, when methylene-spaced alkoxysilanes are used for functionalizing. When an excess of alkoxy groups relative to metal-OH groups are present, the resulting functionalized particles exhibit high reactivity, particularly upon exposure to moisture. Functionalization is particularly useful with particles of organopolysiloxane resins.

    摘要: α-aminoalkoxysilanes wherein the α-amino group is a tertiary amino group, and which also contains a further reactive group, display excellent reactivity of the alkoxy groups while remaining stable with respect to decomposition and byproduct formation, particularly through cleavage of the Si-C bond. The α-aminosilanes are particularly useful for preparing alkoxysilyl-terminated prepolymers which exhibit high cure rates in the presence of moisture, and for functionalizing particles reactive therewith.
