    Abstract - (Show below) - (Hide below)

    Describes two methods for the measurement of the isocyanate content of aromatic isocyanates used as polyurethane raw materials. Method A is primarily applicable to refined toluene diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B is applicable to refined, crude or modified isocyanates derived from toluene diisocyanate, methylenebis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate.
