A polymer composition is provided with a multi-modal molecular weight distribution of a halo-containing polymer. The halo-containing polymer is has multi-functional phosphine linkages at less than 10% of halo sites of the halo-containing polymer that were available before multi-functional phosphine linking. A process for producing a polymer composition having a multi-modal molecular weight distribution involves dispersing a multi-functional phosphine compound in a halo-containing polymer, the halo-containing polymer comprising a total number of available halo sites, and reacting the multi-functional phosphine compound with the halo-containing polymer at an elevated temperature to produce the polymer composition in which less than 10% of the total number of available halo sites are reacted with the phosphine compound to provide multi-functional phosphine linkages in the halo-containing compound.

Polymer compositions having a halo-containing polymer with a multi-functional phosphine linkage

The invention relates to an energy efficient, environmentally favourable process for preparing water and solvent-free rubber ionomers and/or polymer nanocomposites comprising said rubber ionomers.

Process for the production of rubber ionomers and polymer nanocomposites

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.

Process for production of halobutyl ionomers

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.
