  • Polymerization process
    Publication number: 20070043185
    Abstract: A process for the production of polymers in which an oligomeric precursor is formed first in a melt phase. A phase transition is then induced in the polymerizing reaction medium under the action of shear in such a way that the simultaneous action of the shear, and the ongoing polymerization through the phase transition produces a product that is in a powdered form.

  • Enzymatic production of macrocyclic amide oligomers
    Publication number: 20060148044
    Abstract: Hydrolytic enzymes capable of catalyzing amidation reactions can be used to produce cyclic amide oligomers from diesters and diamines. The cyclic amide oligomers are useful for the production of higher molecular weight polyamides.
