This invention relates to a process for producing a polyester comprising the steps of:

Method for making isosorbide containing polyesters

A gum base comprising a crosslinked branched polyester gel prepared from the process comprising: a) providing a first pre-gel composition having carboxyl end groups; b) providing a second pre-gel composition having hydroxyl end groups; c) removing either or both of the first and second pre-gel compositions from their respective reactors; d) combining the first and second pre-gel compositions to form a mixture; and e) processing the mixture in an extruder, a continuous processor, or a container thereby providing a crosslinked branched polyester gel.

Process for crosslinked branched polyesters

Disclosed is a process for the co-production of an aromatic carboxylic esters and alkyl iodide by the carbonylation of an aromatic iodide in the absence of a Bronsted base and in the presence of an ether and a nickel catalyst.
