Polymers and methods for ophthalmic applications
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.
Detergents And Cleaning Products Containing A Polymer Active Ingredient
A compound for improving the primary detergent power of detergents and cleaning products, in particular with respect to soiling containing oil and/or grease. This is achieved essentially by the incorporation of polymers obtainable by polymerization of compounds of the general formula (I), in which R.sup.1, R.sup.2 and R.sup.3, independently of one another, represent H or an alkyl group having 1 to 3 C atoms, with ,-monoethylenically unsaturated carboxylic acids, carboxylic acid esters, carboxylic anhydrides, carboxamides, carboxylic acid imides, nitriles and their mixtures.
Monomer composition and curable composition containing same
Provided is a monomer composition that has rapid curability and can be rapidly cured even in the presence of oxygen and/or water to form a cured product having excellent adhesion to a wide variety of substrates. The monomer composition contains a multifunctional vinyl ether compound in an amount of 10 to 80 weight percent, a bifunctional oxetane compound represented by Formula (b) in an amount of 0.5 to 20 weight percent, and a monofunctional oxetane compound represented by Formula (b) in an amount of 5 to 80 weight percent. In the formulae, Ring Z is selected from an aromatic hydrocarbon ring and a structure including two or more aromatic hydrocarbon rings bonded to each other through a single bond or a linkage group; R represents a monovalent aliphatic hydrocarbon group; R is selected from hydrogen and ethyl; and m represents an integer of 0 or more. ##STR00001##
