When you are polymerizing a urethane prepolymer, and there is solvent used
in the cook plus a significant amount of water in the solvent, do you treat
the calc. of water as 18g/mol or 9g/eq. Water has two active hydrogens, so
isn't its functionality 2? We are having a big lab battle over this point.
Someone out there must have the answer
