Polyesters including isosorbide as a comonomer and methods for making same |
摘要 |
An isotropic polyester polymer and method for making the polyester is prepared by (1) combining in a reactor a monomer containing a terephthaloyl moiety; optionally, one or more other monomers containing an aromatic diacid moiety; a monomer comprising an ethylene glycol moiety; a monomer containing an isosorbide moiety; optionally, one or more other monomers containing a diol moiety; and optionally, a monomer containing a diethylene glycol moiety; with a condensation catalyst suitable for condensing aromatic diacids and glycols; and (2) heating the monomers and catalyst to polymerize the monomers to yield a polyester having an inherent viscosity of at least about 0.35 dL/g.
