Claims
- 1. A process for crosslinking a thermoplastic ethylene silane copolymer which comprises forming said ethylene silane copolymer in a processing zone into a shaped article in the absence of a catalyst, removing said shaped article from said processing zone and thereafter subjecting said thermoplastic ethylene silane copolymer shaped article to a solution of benzoic acid in an amount and for a time sufficient to crosslink said thermoplastic ethylene silane copolymer.
- 2. The process defined in claim 1 wherein the copolymer contains one or more alpha-olefin comonomers and one or more alkenyl alkoxy silane comonomers.
- 3. The process defined in claim 2 wherein the copolymer is an ethylene/vinyl trimethoxy silane copolymer.
- 4. The process defined in claim 1 wherein the copolymer is a silane grafted homopolymer or copolymer or a copolymer of an olefin and a silane.
- 5. A process according to claim 1 wherein said benzoic acid is employed in an amount of about 0.2% to about 3% by weight based on the weight of the solution.
- 6. A process according to claim 1 wherein said benzoic acid is employed in an amount of about 2.5% to about 2.8% by weight based on the weight of the solution.
- 7. A process according to claim 1 wherein said shaped article is submerged in said solution of benzoic acid.
- 8. A process according to claim 1 wherein said shaped article is sprayed with said solution of benzoic acid.
- 9. A process according to claim 1 wherein said shaped article is circulated through said benzoic acid solution.
- 10. A process according to claim 1 wherein said thermoforming operation is an extrusion operation.
- 11. A process according to claim 1 wherein said thermoforming operation is a molding operation.
- 12. A process according to claim I wherein said thermoplastic ethylene silane copolymer contains a mineral filler or carbon black.
