Title: Production of polyester fiber with increased chemical stability
Inventor: YABUKI KAZUYUKI
IPC: D01F6/62
Filed: 1979-03-01
Abstract: PURPOSE: A polyester is treated with an epoxide using a specific trivalent organophosphorus compound as a catalyst to give polyester fibers for tire cords with improved resistance to hydrolysis and aminolysis.  
     CONSTITUTION: When melted, a polyester polymer is treated with an epoxide in the presence of a catalyst of trivalent organophosphorus compound in which all groups connecting with the phosphorus atom are those among aliphatic, aromatic and alicyclic groups, e.g., trialkylphosphine or triarylphosphine to reduce terminal carboxyl groups and then made into fibers, thus giving polyester fibers with improved resistance to hydrolysis and aminolysis. The organophosphorus compound is thought to act as a basic catalyst and the phosphorus atom, after the action, converts from trivalence to pentavalence to lose the catalytic activity of depolymerizing polyesters unlike the alkali metal or amine catalysts.
