    摘要: Organosilicon compounds bearing silicon-bonded organyloxy groups are prepared by mixing and reacting silanol-functional organosilicon compounds with organosilicon compounds containing at least two organyloxy groups in a mixer with an energy input of at least 0.2 kW/Kg of mixture. At this level of energy input, reaction to form the organyloxy-functional product is rapid, and can be achieved without supplying external heat, and also without catalysts, if desired.

    摘要: Alkoxysilane-terminated polymers prepared by reacting an isocyanatoalkoxysilane, preferably an isocyanatodialkyalkoxysilane, with an isocyanate-reactive prepolymer, can provide chain extension even when a monoalkoxy-functional silane, while retaining suitable reactivity profiles. The products are useful in sealants, caulks, coatings, and moldings.
