Alkalinity and CPR value in polyols in accordance with BS ISO 14899

Alkalinity and CPR (controlled polymerization rate) values are very important quality parameters for the polyols used in polyurethane production. Knowledge of these parameters makes it possible to prevent unwanted gelatinization. This Application Note describes automatic and potentiometric titration in accordance with ISO 14899:2001 using hydrochloric acid as the titrant.
