The present invention relates to a process for preparing polyether polyols by addition of alkylene oxides onto H-functional starter substances, characterized in that at least one urethane alcohol of formula (II) where R.sup.1 is linear or branched C.sub.2 to C.sub.24-alkylene which may optionally be interrupted by heteroatoms such as O, S or N and may be substituted, R.sup.2 is linear or branched C.sub.2 to C.sub.24-alkylene which may optionally be interrupted by heteroatoms such as O, S or N and may be substituted, R is H, linear or branched C.sub.1 to C.sub.24-alkyl, C.sub.3 to C.sub.24-cycloalkyl, C.sub.4 to C.sub.24-aryl, C.sub.5 to C.sub.24-aralkyl, C.sub.2 to C.sub.24-alkenyl, C.sub.2 to C.sub.24-alkynyl, each of which may optionally be interrupted by heteroatoms such as O, S or N and/or each of which may be substituted by alkyl, aryl and/or hydroxyl, is used as H-functional starter compound. The invention further provides the polyether polyols containing a urethane group, the polyether polyols obtainable by the process according to the invention, for the use of the inventive polyether polyols for preparation of a polyurethane polymer, and the resulting polyurethane polymers.

The present invention relates to hydrophilic, i.e., water loving coatings (hereafter referred to as WLC). Polyurethane epoxy alkylene oxide coatings usable as coatings on for example, medical devices are a preferred WLC.

A method for producing a narrowly distributed and high-purity polyalkylene glycol derivative having an amino group at an end, a polymerization initiator for use in the method, and a precursor of the polymerization initiator are provided. The present invention provides: a method for producing a polyalkylene glycol derivative having an amino group at an end, using, as a polymerization initiator, a compound represented by the general formula (I); a compound represented by the following general formula (I); and a precursor thereof: ##STR00001## wherein R.sub.A.sup.1a and R.sub.A.sup.1b each independently represent a protective group of the amino group, or one of R.sub.A.sup.1a and R.sub.A.sup.1b represents H and the other represents a protective group of the amino group, or R.sub.A.sup.1a and R.sub.A.sup.1b bind to each other to represent a cyclic protective group forming a ring; R.sub.A.sup.2 represents a linear, branched, or cyclic hydrocarbon group having 1 to 6 carbon atoms; R.sub.A.sup.3 represents a single bond, or a linear, branched, or cyclic hydrocarbon group having 1 to 20 carbon atoms, and the hydrocarbon group may contain a heteroatom; the total number of carbon atoms (or the total number of carbon atoms and heteroatoms) of R.sub.A.sup.2 and R.sub.A.sup.3 is 4 or more; and M represents an alkali metal.

The present invention relates to a process of synthesis of certain ionic liquids di-polymerized based Radziszewsky type reaction, whereby primary amines containing at least one terminal functional group, for example OH, aldehydes and a mineral or organic acid, react exothermically in a single step, thus resulting in an ionic liquid by condensation, then oxirane derivative molar quantities are added, by controlling the temperature and pressure a di-polymerized ionic liquid is obtained. The process of the present invention is advantageous because it provides a synthesis scheme for di-polymerized ionic liquids, primarily using short reaction times and high performance; this process can be further scaled for industrial production and it can accept alternative chemical precursors of lower cost.

An example of the general synthesis scheme of ionic liquids-propoxylated di (LI's) imidazolium follows:

##STR00001##

Whereby an efficiency greater than 96% of propoxylated ionic liquid is obtained, the product characterized by spectroscopic data.
