wherein each R5 is independently selected from the group consisting of alkyl of one to about four carbon atoms, alkoxy of one to about four carbon atoms and halogen, and n is an integer from 0 to 2, with the proviso that if n is 2, then said R5 substituents together contain no more than 6 carbon atoms; R6 is selected from the group consisting of hydroxyalkyl of one to about six carbon atoms and cyclohexylmethyl; and R7 is selected from the group consisting of alkyl of one to about four carbon atoms and hydrogen. These compounds may be used as intermediates for the synthesis of 1H-imidazo[4,5-c]quinoline derivatives.

摘要:Polyurethane synthesis composition using a polymeric emulsifier having a backbone consisting of a copolymer of 4-12C unsaturated dicarboxylic acid or anhydrides and 2-40C olefins, with polyoxyalkylene side chains derived from 2-20C oxiranes. A polyurethane (PU) synthesis composition containing, as emulsifier, a polymer (T) with (at least) a copolymer backbone (TR) derived from 4-12 carbon(C) unsaturated dicarboxylic acid(s) and/or their anhydrides (TR1) and 2-40 C olefin(s) (TR2), and having polyalkylene oxide side chain (TP) derived from 2-20 C oxirane(s) (TP1), together with at least two compounds (a) comprising at least two reactive hydrogen atoms, at least one of which is insoluble. Independent claims are also included for: (a) a process for the production of synthesis composition by contacting the components in presence of a polymer; (b) a PU synthesis composition obtained; (c) a polyurethane obtained by bringing the synthesis composition into contact with a polyisocyanate; and (d) moldings, fibers, coatings, paint, sheets and a foam made from the PU compositions.
