摘要：
Disclosed is to prevent generation of byproducts or a deterioration in the physical properties of a polythiol composition that may be caused by active oxygen during storage thereof by way of controlling the content of active oxygen in the polythiol composition after the synthesis of the polythiol. As a result, it is possible to enhance the long-term storage stability of a polythiol composition after it has been synthesized until it is used in the polymerization reaction.
