Abstract:
Process for the preparation of polyether polyols, which process comprises: (b) contacting a phosphorus containing compound having at least one hydroxyl group with alkylene oxide to obtain alkoxylated initiator, (b) contacting the alkoxylated initiator with further alkylene oxide in the presence of a double metal cyanide complex catalyst.
Abstract:
The present invention is directed to a coating composition comprising polyurea formed from a reaction mixture comprising: (a) a first component comprising isocyanate, wherein said isocyanate comprises an isocyanate functional prepolymer formed from a reaction mixture comprising isocyanate and a material comprising a phosphorus-containing polyol; and (b) a second component comprising an amine.
Abstract:
The present invention relates to design - and installation-time tool for solving the inrush problem. The proposed design and planning tool for power distribution networks, especially DC (Direct Current) networks, takes into account the inrush behavior of the loads (10a, 10b) and distributes the loads likely to be switched on at the same time (e.g. being members of one control group) to different bus bars (20a, 20b, 20c).
