IndependentBNpoly(ethylene terephthalate)
A method of preparing a polymer composition, the method comprising a) providing a reactant mixture comprising a ﬁrst monomeric or oligomeric reactant and exfoliated hexagonal boron nitride; and b) polymerizing the ﬁrst monomeric or oligomeric reactant in the reactant mixture to form the polymer composition that includes dispersed platelets of exfoliated hexagonal boron nitride; wherein the polymer is selected from the group consisting of polyesters, polyamides, polyimides, poly u rethanes, polycarbonates, and mixtures and copolymers thereof.
