I. Product property: Propylene oxide is a colorless transparent liquid at room temperature and atmospheric pressure, has an odor similar to ether odor and is active chemically; additionally, propylene oxide is of easy ring opening polymerization and can react with water, ammonia, alcohol and carbon dioxide to generate corresponding compounds or polymers. The polymer is generated from polymerization on the compound containing over two active hydrogen agents that are called polyether polyol.
