MACROMER AND PROCESS FOR MAKING POLYMER POLYOLS
Polyether polyols are prepared by polymerizing unsaturated monomers in a continuous phase of a base polyol. A macromer or polymerization produce of such a macromer is present during the polymerization to stabilize the polymer particles as they form. The macromer is a polyether capped with certain unsaturated epoxide compounds.

ALKYLENE OXIDE POLYMERIZATION USING ALUMINUM COMPOUNDS AND PHOSPHORUS-NITROGEN BASES
Polyethers are prepared by polymerizing an alkylene oxide in the presence of a starter, an aluminum compound that has at least one hydrocarbyl substituent, and a phosphorus-nitrogen base. The phosphorus-nitrogen base is present in only a small molar ratio relative to the amount of starter. The presence of such small amounts of phosphorus-nitrogen base greatly increases the catalytic activity of the system, compared to the case in which the aluminum compound is used by itself. The product polyethers have low amounts of unsaturated polyether impurities and little or no unwanted high molecular weight fraction. Polymers of propylene oxide have very low proportions of primary hydroxyl groups.
Composition containing modified bisphenol F
The invention relates to a composition that contains a binary mixture of bisphenol F and propoxylated bisphenol F. The aim of the invention is to provide aromatic polyols for preparing polyurethane-based and polyisocyanurate-based polymers, which ensure good handling from a technical point of view and good miscibility with the isocyanate component and render the end product flameproof. For this purpose, the invention devises a composition, which contains a binary mixture of ethoxylated bisphenol F and propoxylated bisphenol F in a weight ratio of 20:80 to 80:20.
