  • Patent number: 9000102
    Abstract: The invention is directed to a process for preparing a linear or branched amine-modified thermoplastic resin with high flowability using as starting materials a linear or branched polyester and a primary or secondary aliphatic amine. The process does not require that the amine and polyester be combined in a liquid organic solvent during the process, and can be performed readily at ambient pressure. The amine-modified resins can be extruded and pelletized using normal operating conditions, making this process a versatile option for achieving a wide variety of viscosities in a simple, low cost, continuous operation.
