The properties of propylene oxide are detailed in Table 3. In general, this compound should be handled in the same manner as ethylene oxide. C— Uses The largest use of propylene oxide is in the manufacture of polyols for polyurethane production. These propylene oxide polyols are propoxylates of low-molecular-weight polyhydroxy compounds such as glycerine or some sugars or polyamines. The propoxylation is catalyzed by caustic, usually potassium hydroxide, and the resulting polyols have molecular weights from a few hundred to 5000 or 10,000 and have hydroxyl functionalities (average number of hydroxyl end groups per molecule) of more than 2 and usually of 3 to 6.

Finally, in 1940, Paul Flory (11) described the kinetics of the base-initiated polymerization of the cyclic ethers such as ethylene oxide and showed that the kinetics predicted a narrow distribution of polymer molecular weights. Experiments verified this prediction of a Poisson distribution of molecular weights. This distribution predicts that, as the average polymer molecular weight becomes large, the ratio of the weight to number average molecular weight approaches unity, provided certain reaction conditions are met: All reaction chains are initiated simultaneously.
