The present invention relates to radiation curable silicone vinyl ethers and methods for preparing silicone vinyl ethers. More particularly, the present invention relates compositions containing vinyl ether functional silicones and to the preparation and use of silicone vinyl ethers which are curable by addition of photocleavable acids and exposure to ultraviolet or electron beam radiation.

Radiation curable siloxane compositions containing vinyl ether

A method for altering a macroporous cross-linked hydrophobic copolymeric lattice produced by precipitation polymerization in a solvent of at least one monounsaturated ester monomer and at least one polyunsaturated ester monomer soluble therein, in order to render the hydrophobic copolymeric lattice hydrophilic. The method involves saponifying the hydrophobic copolymeric lattice by reacting the surface of the hydrophobic copolymeric lattice with an aqueous alkali. The surface can also be rendered hydrophilic by polymerizing an acrylate monomer onto the lattice in order to form a surface containing carboxylic acid sites. The carboxylic acid sites formed on the surface of the lattice are converted to carboxylate anions.

Radiation curable compositions containing vinyl ether functional

The present invention relates to compositions comprising vinyl ether functional siloxanes and aromatic iodonium salt or aromatic sulfonium salt photoinitiators which cure upon exposure to ultraviolet or electron beam radiation. The present invention further relates to use of these compositions in pressure sensitive release applications.

Pyrene based fluorescent organopolysiloxanes which bear two or more reactive silicon-bonded sites are useful as durable markers and indicators of the degree of cure in curable silicone compositions. Having more than one reactive site the compounds participate in the curing reaction of the curable composition and thus do not adversely affect its curing behavior. The resulting fluorescent curable compositions are particularly useful in the preparation of adhesive-release coatings.

Curable fluorescent organopolysiloxane compositions

An antiperspirant product contains as components at least one material selected from the group consisting of astringent antiperspirant compounds, a volatile silicone, a suspending agent, a waxy material, emollients, perfumes, and coloring agents used in making antiperspirants. The improvement relates to the formation of a gel by incorporating in the product a gelling agent which is an organic compound including polycyclic aromatic and steroidal groups linked through ester linkages. A method of forming thermally irreversible organosilicon gels is also described.

A method for enhancing the dielectric properties of a new or in-service electrical cable is disclosed, the method comprising supplying the interstitial void space of the cable's conductor with a water-reative antitreeing agent having a diffusion coefficient of at least 1.times.10.sup.-7 cm.sup.2 /second at 50.degree. C. in the insulation of the cable and having an initial viscosity of .ltoreq.100 cP at 25.degree. C. The instant method provides a more symmetrical distribution of dielectric enhancing fluid in the insulation than prior art fluids and results in a significant reduction in cable treatment time.

Method for enhancing the dielectrical strength of cable using a fluid

A fluorescent organosilicon compound derived from the reaction of an aminofunctional organopolysiloxane and a fluorescent labeling reagent in which the fluorescent labeling reagent is incorporated into the molecule of the aminofunctional organopolysiloxane by means of a sulfonamide linkage. A method of treating hair is also disclosed in which the fluorescent organosilicon compound is applied to hair and the treated hair is examined for fluorescence under ultraviolet light in order to determine the extensiveness of deposition of the fluorescent organosilicon compound.
