摘要：
A polyester, wherein pendent phosphorus atoms are bound to the main chain of the polyester, having an excellent flame resistance and a high intrinsic viscosity can be stably produced without deteriorating the properties of said polyester by preliminarily copolymerizing a polyester with a specific unsaturated compound and then reacting the unsaturated bond thus-formed with a specific phosphorus compound having a P-H bond.
