Abstract

L'invention se rapporte à des concentrés obtenus par transformation par fusion d'un agent de ramification et d'un support de polyester. Les concentrés sont utilisés dans la transformation par fusion des polyesters. Les concentrés renferment des concentrations en agent de ramification suffisamment élevées pour minimiser la formation de composés réticulés dans les concentrés. L'invention se rapporte également à un procédé d'utilisation de ces concentrés.
