PROCESS FOR THE PRODUCTION OF MODIFIED BUTYL RUBBER |
| 摘要 |
There is provided a process for producing an ionomer comprising the steps of (a) admixing in a mixer a halogenated copolymer with at least one nitrogen and/or phosphorus based nucleophile and (b) extruding the mixture from step (a). The process takes place with high conversion and the resulting ionomer contains a low amount of residual nucleophile and has a low yellowness index. |

1. A process for producing an ionomer, the process comprising:
(a) admixing in a mixer a halogenated copolymer with 0.01 to 1.1 molar equivalents of at least one nitrogen and/or phosphorous based nucleophile based on the total allylic halide content of the halogenated copolymer, at a temperature of 40 to 200° C. for 0.5 to 30 minutes to form a mixture; and (b) extruding the mixture from step (a) at a temperature of 50 to 200° C. for 0.5 to 30 minutes and/or milling the mixture from step (a) in a multi roll mill, for about 0.5-90 minutes at a temperature of 50 to 200° C. |
