Novel methods and materials particularly useful for ophthalmic applications and to methods for making and using the same are disclosed herein. More particularly, relatively soft, optically transparent, foldable, high refractive index materials particularly suited for use in the production of intraocular lenses, contact lenses, and other ocular implants and to methods for manufacturing and implanting IOLs made therefrom are disclosed.

Disclosed are a method for a preparing fluorine- and chlorine-containing conductive polymer resin, a single-side or double-side filled composite film prepared using the fluorine- and chlorine-containing conductive polymer resin, and a method for preparing the film. The fluorine- and chlorine-containing conductive polymer single-side or double-side filled composite film comprises a microporous film skeleton and the fluorine- and a chlorine-containing conductive polymer resin. The composite film is mechanically stronger, more waterproof, more impervious to water and toxic and harmful chemicals, and more moisture permeability. When applied to biochemical protective clothing, it can greatly enhance the combat effectiveness of the soldiers because it is light and more impervious to water and toxic and harmful chemicals, brings about comfort, and keeps the soldiers warm. When applied to fuel cells, it can provide better electrical properties due to its high conductivity and can allow the fuel, such as hydrogen or alcohol, to burn more completely.

The present invention provides polymers comprising units of formula (1) as well as compositions comprising the polymers, processes for the preparation of the polymers, electronic devices comprising the polymers, and processes for the preparation of the electronic devices, and the use of the polymers as dielectric materials.

The invention provides a laminate in which a fluororesin layer and a rubber layer are firmly bonded to each other and the fluororesin layer has low fuel permeability and is less likely to suffer solvent cracking. The laminate includes a rubber layer (A) and a fluororesin layer (B). The fluororesin layer (B) contains a copolymer containing a chlorotrifluoroethylene unit, a tetrafluoroethylene unit, and a perfluoroalkyl vinyl ether unit. The copolymer contains 96.0 to 97.4 mol % of the chlorotrifluoroethylene unit and the tetrafluoroethylene unit relative to all the monomer units constituting the copolymer and 2.6 to 4.0 mol % of the perfluoroalkyl vinyl ether unit relative to all the monomer units constituting the copolymer.

Provided herein are processes for the generation of composite polymer materials utilizing a single resin. The processes utilize diffusion between a region undergoing a polymerization reaction preferentially polymerizing one monomer component and an unreactive region. Diffusion and subsequent/concurrent polymerization results in a higher concentration of the more reactive monomer component in the reacting region and a higher concentration of the less reactive monomer components in the unreactive region. The unreactive region may be later polymerized. In embodiments, photopolymerization is used and the regions are generated by a mask or other mechanism to pattern the light.

The present invention relates to the use of hydrophobically associative copolymers as binders for pelletizing metal containing ores such as iron containing ores. The copolymers comprise monomer units derived from at least one hydrophobically as sociative monomer, preferably at least one unsaturated hydrophobically associating monomer.
