A process for effecting flame retardation of fibrous structures, such as fabrics, particularly fabrics made from mixtures of natural and synthetic fibers, such as cotton and nylon. The process includes the steps of contacting the fabric to be treated with halomonomers and/or inorganic salts, followed by fluorocarbon grafting, and then by photohalogenation. The aforesaid treatment results in fabrics which are not only flame resistant but also have improved hand, manifested by softness, silkiness, and unwettability of the resulting fabric.

Process for imparting flame retardancy to fabrics

A method for polymerizing octafluoronaphthalene and the resulting perfluorocompounds prepared therefrom. Polymerization is accomplished by reacting the octafluoronaphthalene monomer with a mono or difluoroxyperfluoroalkane.

Copolymers from octafluoronaphthalene

Perfluorocompounds

An improved process and apparatus is provided for imparting chemically bonded fluorocarbon finishes to textiles. In the process, the textiles are contacted with a gaseous mixture of fluoroolefins in an inert diluent gas in the presence of ultraviolet light under predetermined conditions.

Method and means for producing fluorocarbon finishes on fibrous

A process for producing aromatic polyamides having improved nonflammability characteristics in which a polyamide substrate is contacted with a gaseous medium comprising a minor amount of a haloolefinic material and an inert diluent in the presence of light having sufficient energy to effect chemical addition of the haloolefin to said polyamide substrate.

Vitra-violet process for producing flame resistant polyamides and

A method for synthesizing perfluoropolyethers by effecting addition reactions under low temperature photolysis between perfluoroolefins, perfluorodialkyl peroxides and fluoroxyperfluoroalkanes resulting in the snythesis of new compounds.

Perfluoroethers

A method for synthesizing perfluoropolyethers by effecting addition reactions under low temperature photolysis between perfluoroolefins, perfluorodialkyl peroxides and fluoroxyperfluoroalkanes resulting in the synthesis of new compounds.

Method for the preparation of perfluoroethers

A method for synthesizing bis(perfluoro-t-butyl) peroxide through the photolysis of perfluoro-t-butyl hypofluorite in the presence of tetrafluorohydrazine.
