Cable wire prepared using distannoxane catalysts
View Patent ↗A fabricated article (e.g., jacketed or insulated wire or cable) is prepared by a process comprising the steps of: applying a coating of a moisture-curable composition onto a wire or cable; and reacting the moisture-curable composition with water, wherein the moisture-curable composition comprises at least one resin having hydrolysable reactive silane groups and a tin catalyst characterized by the tin having a +4 oxidation state and a bis(alkoxide) ligand. The product of the process includes a wire or cable comprising a jacket, wherein the jacket comprises at least one poly olefin resin having hydrolysable reactive silane groups and a tin catalyst, the tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state. The product of the process also includes a wire or cable comprising a jacket wherein the jacket comprises (i) the reaction product of at least one polyolefin resin having hydrolysable reactive silane groups and water, and (ii) at least one tin catalyst, the tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state.
1. A wire or cable comprising one or more of a jacket, insulation or semi-conductive layer wherein the jacket, insulation or semi-conductive layer comprises a moisture-curable composition comprising at least one polyolefin resin having hydrolysable reactive silane groups and a distannoxane tin catalyst, the distannoxane tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state, and the polyolefin resin is a copolymer of poly(ethylene-co-octene) and a hydrolysable silane.
2. The wire or cable of claim 1 wherein the distannoxane tin catalyst is penta-coordinate or hexa-coordinate.
3. The wire or cable of claim 2 , wherein the distannoxane catalyst is 2,2-Di-n-butyl-1,3,2-dioxastannolane.
4. A wire or cable comprising a jacket wherein the jacket comprises a moisture-curable composition comprising (i) the reaction product of at least one polyolefin resin having hydrolysable reactive silane groups and water, and (ii) at least one distannoxane tin catalyst, the distannoxane tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state, and the polyolefin resin is a copolymer of poly(ethylene-co-octene) and a hydrolysable silane.
5. The wire or cable of claim 4 wherein the distannoxane tin catalyst is penta-coordinate or hexa-coordinate.
6. The wire or cable of claim 4 , wherein the distannoxane is 2,2-Di-n-butyl-1,3,2-dioxastannolane.
7. A process for preparing a jacketed wire or cable, the process comprising the steps of: applying a coating of the moisture-curable composition of claim 1 onto a wire or cable; and reacting the moisture-curable composition with water.
8. The process of claim 7 wherein the distannoxane tin catalyst is penta-coordinate or hexa-coordinate.
9. The process of claim 8 , wherein the distannoxane is 2,2-Di-n-butyl-1,3,2-dioxastannolane.
10. The process of claim 7 further comprising the step of producing the distannoxane tin catalyst in situ by a condensation reaction of an alkyltin oxide and a diol.
11. The process of claim 10 , wherein the diol is at least one of: 1,3-propanediol; 1,2-propanediol; ethylene glycol; or 1,5-pentanediol.
12. An article of manufacture comprising a moisture-curable composition comprising at least one polyolefin resin having hydrolysable reactive silane groups and a distannoxane tin catalyst, the distannoxane tin catalyst having a bis(alkoxide) ligand and characterized by the tin having a +4 oxidation state, and the polyolefin resin is a copolymer of poly(ethylene-co-octene) and a hydrolysable silane.
13. The article of manufacture of claim 12 wherein the article is selected from the group consisting of wire-and-cable insulations, wire-and-cable semiconductive articles, wire-and-cable coatings, wire-and-cable jackets, cable accessories, shoe soles, multicomponent shoe soles, weather stripping, gaskets, profiles, durable goods, rigid ultradrawn tape, run flat tire inserts, construction panels, composites, pipes, foams, blown films, and fibers.
14. A process for preparing the article of manufacture of claim 12 , the process comprising the step of reacting the moisture-curable composition with water.
