摘要:
The invention relates to an energy efficient, environmentally favorable process for the preparation of butyl ionomers that uses a common medium for both solution polymerization and subsequent bromination of butyl rubber. More particularly, the invention relates to a process that employs a common aliphatic medium for both solution polymerization and bromination of butyl rubber in the presence of a brominating agent and optionally for subsequent reaction with at least one nitrogen and/or phosphorus based nucleophile.
摘要:
The invention relates to a processes for preparing nanocomposites comprising rubber ionomers which were prepared by an energy efficient, environmentally favorable process that uses a common medium for solution polymerization, bromination of rubber and optionally subsequent polymer nanocomposite formation. Polymer nanocomposites according to the present invention exhibit high oxygen impermeability.

摘要:
The present invention relates to ionomers comprising a reaction product of the reaction between a halogenated isoolefin copolymer and at least one phosphorus based nucleophile comprising at least one pendant vinyl group. The present invention also relates to a method of preparing and curing these ionomers.
摘要:
The present invention relates to processes for recycling articles made from butyl ionomers and processes for producing recycled butyl ionomers. The invention further relates to composites comprising recycled butyl ionomers and fillers and articles made from recycled butyl ionomers. The invention also relates to uncured filled articles made from butyl ionomers having certain physical properties. Exemplary fillers include silica, carbon black, talc and clay, particularly onium substituted high aspect ratio nanoclays.
