| titleOfInvention | Process for making a modified thermoplastic polyester |
| abstract | The invention relates to a process for making a modified thermoplastic polyester by reacting a thermoplastic polyester with a nitrogen-containing compound, wherein the thermoplastic polyester is first contacted in the solid state with an inert gas atmosphere containing at least one amino-compound of formula H 2 N—R—(X) n , wherein n is an integer≧0, R=a linear, branched or cyclo-aliphatic or aromatic residue comprising 1–24 C-atoms and optionally containing hetero atoms, X═—NH 2 or another functional group reactive with the polyester, at a temperature T(a) between room temperature and the melting point T m of the polyester, during at least 1 s; and then heated to a temperature T(b) between T(a) and T m , during up to 10 hours; and thereafter solid state polymerized at a temperature T(c) between (T m −50) and T m , during up to 100 hours, where T(a)<T(b)<T(c). n The process according to the invention allows making a modified thermoplastic polyester in a relatively simple way, and can easily be applied to an existing polyester polymerization process, such that in addition to an unmodified thermoplastic polyester, a modified thermoplastic polyester can be produced starting from the same existing pre-polymer. With the process according to the invention properties like the crystallization behaviour can be adjusted in a customized way. Depending on the type of amino-compound that is used, a thermoplastic polyester with higher or lower crystallization rate may be made, whereas the amount of amino-compound used affects the degree of (crystallization) modification. Also other properties of the thermoplastic polyester may be modified, like its rheological behavior or its dyeability. |
