US Patent:

62621815, Jul 17, 2001

Filed:

Dec 22, 1999

Appl. No.:

9/469379

Inventors:

Nageshwer Rao Bantu - Barrington RI
Donald Frank Perry - North Providence RI
Jacqueline Marie Marshall - Tiverton RI
Timothy Michael Holt - Providence RI

Assignee:

Arch Specialty Chemicals, Inc. - Norwalk CT

International Classification:

C08F26102

US Classification:

525262

Abstract:

This invention relates to a process for generating a organically soluble partially cross-linked acid labile polymer according to the present invention comprises the steps of providing a polymer with one or more monomer units, wherein at least one of the monomer units contain one or more pendant COOH or hydroxyl groups; and reacting said polymer with a polyvinyl ether in the presence of a acid catalyst to form links between at least two polymer chains. The resulting polymer can be used as a component in a photoresist formulation.

B65D 8500

US Classification:

206223

Abstract:

A cable repair kit including the component parts thereof and a process for repairing in the field simply and quickly high-voltage electrically conductive cables whose outer jackets have been damaged but whose inner conductors have not been damaged. The kit comprises a portable container sealingly enclosing abrasive material for abrading the damaged cable portion; a cleaning compound; a filler compound for restoring or filling in the damaged region of the cable jacket; a bonding agent for bonding a patch of insulative, flexible material circumferentially about the section of the cable wherein the damaged portion is located; the insulative patch material; and a flame-resistant tape for aiding the bonding agent in joining the patch to the cable, as well as providing the patch with a smooth and continuous surface at a junction between side edges thereof and the cable surface.
