Abstract
In the report the liquid-repellent properties of the homopolymers and selected copolymers of ten fluoroalkyl-substituted silane monomers of varying structures are evaluated. The homopolymers of the silanes are synthesized, applied to nylon/cotton (50:50 weight per cent) and cotton as finishes, and the oil and water repellency imparted to these fabrics ascertained by standard tests. Due to the expense of these fluorinated materials, a study was conducted of the copolymerization of the best fluoroalkyl-substituted silanes with much cheaper non-fluorinated alkyl silanes. The oil and water repellencies obtained with both the homopolymers and copolymers ranged from outstanding to essentially none.
