Abstract: The present invention provides a process for the production of an N,N-dialkylaminophenyl alkanol having the formula: ##STR1## in which R.sub.1 and R.sub.2, independently, are C.sub.1 -C.sub.4 alkyl, R.sub.3 is hydrogen, halogen, cyano, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy and n is an integer from 1 to 4, comprising reacting an aminophenyl alkanol having the formula: ##STR2## in which R.sub.3 and n have their previous significance, with at least two moles of a dialkylsulfate having the formula: ##STR3## in which R.sub.1 and R.sub.2 have their previous significance. N,N-dialkylaminophenyl alkanols so obtained are valuable as intermediates for a wide range of end-products and are also useful, e.g., as accelerators for the peroxide-catalyzed polymerization of vinyl monomers, especially in polymerizable or curable formulations employed in dental applications.

Abstract: Propylene oxide is added to an active hydrogen compound in the presence of an alkali metal hydroxide catalyst in an amount of from 0.05 to 0.5 mole per mole of the active hydrogen compound at a reaction temperature of from 60.degree. to 98.degree. C. at a reaction pressure less than or equal to 4 kg/cm.sup.2 to prepare a polyoxyalkylene polyol which has a hydroxyl value of from 10 to 35 mg KOH/g, a monool content less than or equal to 15 mol %, a Head-to-Tail bond selectivity greater than or equal to 96 percent, and low viscosity. A polymer polyol is prepared by polymerizing an ethylenically unsaturated monomer in the polyoxyalkylene polyol. A flexible polyurethane foam is prepared by reacting the polyoxyalkylene polyol or the polymer polyol with an organic polyisocyanate compound in the presence of a foaming agent, a catalyst, a surfactant, a crosslinking agent and other additives.
