Assignee:

E I DU PONT DE NEMOURS AND COMPANY - Wilmington DE

International Classification:

C08K 9/06

US Classification:

524188

Abstract:

This invention relates to compositions comprising blends of acrylic add polymers and/or ethylene acrylic add copolymers and colloidal silica modified with certain aromatic aminosilanes, aromatic aminoalkylsilanes, alkenyl aminoalkylsilanes, secondary or tertiary aliphatic aminosilanes. These compositions can provide improved properties such loss modulus, storage modulus, creep resistance, and wear resistance, without sacrificing optical clarity.

US Classification:

430/204000

Abstract:

A photosensitive element for use as a flexographic printing plate comprises a support, an elastomeric photopolymerizable layer having a surface opposite the support that defines a plane, and a matted layer disposed above the surface of the photopolymerizable layer comprising a polymeric binder and at least one matting agent which is capable of forming depressions from the plane into the photopolymerizable layer. Also described is a process for preparing such a photosensitive element and a process for preparing a flexographic printing plate from the photosensitive element.

Abstract:

The invention provides a polymer-polymer composite polishing method comprising a polishing layer having a polishing surface for polishing or planarizing a substrate. The method includes attaching a polymer-polymer composite having a polishing layer and a polymeric matrix. The polymer matrix has fluoropolymer particles embedded in the polymeric matrix. Then a cationic particle slurry is applied to the polymer-polymer composite polishing pad. Conditioning the polymer-polymer composite polishing pad with an abrasive cuts the polymer-polymer composite polishing pad; and rubbing the cut polymer-polymer composite polishing pad against the substrate forms the polishing surface. The polishing surface has a fluorine concentration measured in atomic percent at a penetration depth of 1 to 10 nm of at least ten percent higher than the bulk fluorine concentration measured with at a penetration depth of 1 to 10 μm to polish or planarize the substrate.

Abstract:

The invention provides a polymer-polymer composite polishing pad comprising a polishing layer having a polishing surface for polishing or planarizing a substrate. A polymeric matrix forms the polishing layer. Fluoropolymer particles are embedded in the polymeric matrix. Wherein diamond abrasive materials cut the fluoropolymer particles and rubbing the cut fluoropolymer against a patterned silicon wafer forms a thin film covering at least a portion of the polishing layer and the thin film has a zeta potential more negative than the polymeric matrix at a pH of 7. The polishing surface formed from rubbing with the wafer has a fluorine concentration at a penetration depth of 1 to 10 nm of at least ten atomic percent higher than the bulk fluorine concentration at a penetration depth of 1 to 10 μm.

Abstract:

A voltage detecting glove comprises a glove liner and an outer glove shell. A conductive antenna is disposed inside the outer glove shell but separated from the glove liner by a buffer. The antenna is connected to electronic circuitry configured to sense a voltage indicative of the proximity of the antenna to an AC electric field resulting from energized AC source, and to activate an alarm if the strength of the field exceeds a preselected threshold limit.
