【発明の名称】固相重合によるポリマーの製造方法

Document Type and Number:

Japanese Patent JP2003521560

Kind Code:

A

Abstract:

Solid state polymerization of polycarbonates and polyesters is preceded by a step of contacting particles of an amorphous precursor polymer with a particulate material, typically a crystallized polycarbonate, which prevents adherence of the precursor polymer particles to each other. It is then possible to perform the solid state polymerization step without crystallizing the precursor polymer.
