title: [The measurement of the ratio of primary hydroxyl group to second hydroxyl group in polyether polyol by near infrared spectrum].
abstract: The method of near infrared spectrum, combined with derivative spectrum and multiple linear regression was applied to measure the ratio of primary hydroxyl group to second hydroxyl group in polyether polyol. The authors obtained good predictive results by using the method in this experiment. The work is very helpful for the on-line measurement of polyether polyol.
