Method for increasing solid state polymerization rate of polyester polymers |
abstract |
This invention concerns a method for increasing the polymerization rate of polyester polymers in the solid state by adding a catalytic amount of zinc p-toluenesulfonate to a polyester polymer melt that is essentially free of antimony and germanium, before solid state polymerization. |
