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.
Claims20
An ionomer comprising a reaction product of a reaction between:
- a) halogenated isoolefin copolymer comprising repeating units derived from at least one isoolefin monomer and repeating units derived from one or more multiolefin monomers;
- 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 weight 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 halogenated isoolefin copolymer comprises repeating units derived from at least one isoolefin monomer and repeating units derived from one or more multiolefin monomers,
- 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, and
- a weight ratio of the first nucleophile to the second nucleophile is 4:1 to 100:1;
- and
- reacting halogen moieties of the halogenated copolymer with the nucleophiles to form the ionomer.
