Abstract
The present invention relates to ionomers comprising a reaction product of the reaction between a) a halogenated isoolefin copolymer and b) a nucleophile having no pendant vinyl group and a nucleophile comprising at least one pendant vinyl group. The present invention also relates to a method of preparing and curing these ionomers.
Claims39
An ionomer comprising a reaction product of a reaction between:
- a) halogenated isoolefin copolymer;
- and
- b) nucleophiles comprising at least one first nucleophile having no pendant vinyl group, and at least one second nucleophile comprising at least one pendant vinyl group;
- wherein a ratio of the first nucleophile to the second nucleophile is 4:1 to 100:1.

A process for preparing an ionomer, the process comprising:
- contacting a halogenated isoolefin copolymer and
- nucleophiles to produce a reaction mixture, wherein the nucleophiles comprise at least one first nucleophile having no pendant vinyl group and at least one second nucleophile comprising at least one pendant vinyl group at a ratio of the first nucleophile to the second nucleophile of 4:1 to 100:1;
- and
- reacting halogen moieties of the halogenated copolymer with the nucleophiles to form the ionomer.

A process for preparing a cured polymer, the process comprising:
- contacting a halogenated isoolefin copolymer with
- nucleophiles to produce a reaction mixture, wherein the nucleophiles comprise a first nucleophile having no pendant vinyl group, and a phosphorus containing nucleophile comprising at least one pendant vinyl group;
- reacting halogen moieties of the halogenated copolymer with the nucleophiles to form the ionomer;
- and
- curing the ionomer by heating at a curing temperature.
