Abstract
Fiber-forming polyhydrazides prepared from oxalic dihydrazide, terephthalic dihydrazide, malonic dihydrazide and terephthaloyl chloride are provided. Yarns made from these polyhydrazides are useful in tire cord applications and retain greater tenacity when plied into cord than yarns made from corresponding polyhydrazides from which the malonic dihydrazide has been omitted.
