Fluoroalkyl Siloxanes as Liquid-Repellent Fabric Finishes. Part 1. A state-of-the-Art Review and Synthesis of the Monomers
Abstract
This project concerns the evaluation of fluoroalkyl-substituted siloxane polymers as liquid-repellent finishes. First, a brief literature review is given on the current state of the art of these finishes. Second, syntheses and properties for a family of ten fluoroalkyl silanes are reported. These monomers include the best of those utilized in the literature as well as several new ones chosen to elucidate the effect of structure on liquid repellent properties. A second report will describe the method of polymerization, the liquid repellency values obtained with the homopolymers, and the results of copolymerizations with the much cheaper non-fluorinated silanes.
