Abstract
A method for forming a polyaryletherketone is described. More particularly, a reaction mixture is initially supplied to the reactor vessel that contains one or more precursor monomers. A heteroaryl compound is also added to the reaction mixture. The reaction can be carried out according to, e.g., an electrophilic aromatic substitution reaction or a nucleophilic aromatic substitution reaction. The heteroaryl compound can serve as a dispersant to the polymer as it is formed. This minimizes the likelihood of gelling of the product polymer within the reactor vessel and limits the impact of process disruptions on the production of the polyaryletherketone.
Claims30
A method for forming a polyaryletherketone, the method comprising:
- supplying one or more monomers to a reactor vessel to form a reaction mixture, wherein the one or more monomers are precursors for the polyaryletherketone, and at least one of the one or more monomers is a halide-containing monomer;
- introducing a heteroaryl compound into the reactor vessel;
- and
- the one or more monomers reacting with one another in the presence of the heteroaryl compound to form the polyaryletherketone.
A polyaryletherketone formed according to a method comprising supplying one or more monomers to a reactor vessel to form a reaction mixture, wherein the one or more monomers are precursors for the polyaryletherketone, and at least one of the one or more monomers is a halide-containing monomer, and introducing a heteroaryl compound into the reactor vessel.
