Analysis of dissolution modes of partially protected poly(4-hydroxystyrene) in tetraalkylammonium hydroxide aqueous solutions using decision trees and support vector machine

To investigate the development kinetics, this study categorized the dissolution dynamics in tetraalkylammonium hydroxide (TAAH) aqueous solutions into six classes based on frequency and impedance variations during the development process using quartz crystal microbalance (QCM) measurements. These classifications were examined against various material attributes via decision trees and support vector machine (SVM) models. The feature values included in this analysis comprised the length of alkyl chains, molecular weight, solute concentration, viscosity of developers, protection ratios, molar masses, contact angles, and surface free energy of polymer. Accuracy for the test dataset was approximately 0.80 and 0.75 for the decision trees and SVM, respectively, when validated.
