    Abstract: A polyester is used as an elastomer component for gum bases. A method of making gum bases which include such polyesters is also disclosed. The polyester includes as polyester-forming components in condensed form; a) at least one aliphatic dicarboxylic acid; b) at least one aliphatic diol; and c) at least one compound having at least three groups capable of ester formation in an amount of from 0.1 to 10.0% by weight, based on the total weight of the polyester, wherein the polyester includes the components a) and b) in an amount of at least 90, in particular at least 95% by weight, based on the total weight of the polyester.

    Abstract: A process is described for functionalizing isobutene polymers having terminal olefinic unsaturation by treating with the reaction product of a borane source with from 0.5 to 1.8 equivalents of an alkene having a molecular weight of less than 250 per mole of borane or by treating the isobutene polymer with the borane source in the presence of the alkene. The reaction mixtures retain low viscosity and good stirrability.
