Process of manufacturing polyols

A method of producing a polyurethane product, the method comprising:

• producing a polyether polyol by reacting a low molecular weight initiator with ethylene oxide in the presence of a polymerization catalyst, the low molecular weight initiator having a nominal hydroxyl functionality at least 2, and the polymerization catalyst being a Lewis acid catalyst having the general formula M(R1)1(R2)1(R3)1(R4)0 or 1, whereas M is boron, aluminum, indium, bismuth or erbium, R1, R2, R3, and R4 are each independent, R1 includes a first fluoroalkyl-substituted phenyl group, R2 includes a second fluoroalkyl-substituted phenyl group or a first fluoro or chloro-substituted phenyl group, R3 includes a third fluoroalkyl-substituted phenyl group or a second fluoro or chloro-substituted phenyl group, and optional R4 includes a functional group or functional polymer group, R1 being different from at least one of R2 and R3;
• the polyether polyol having a number average molecular weight of greater than the number average molecular weight of the low molecular weight initiator in the presence of the Lewis acid catalyst;
• and
• providing an isocyanate.
