Perfluorinated alkyl hydrophobe hydroxyalkylcellulose associative thickeners.

摘要

A purified hydroxyethylcellulose (HEC) or hydroxypropylcellulose (HPC) reacts with a perfluorinated alkyl glycidyl ether to produce an associative thickener wherein a fluorinated C8 chain is nearly as effective as a hydrocarbyl C16 straight chain hydrophobe. A preferred glycidyl ether is prepared by reacting a terminal hydroxyl of a perfluorinated surfactant with epichlorohydrin.
