Abstract
The present disclosure provides a composition for preparing a vinyl chloride-based polymer, including a vinyl chloride-based first seed; a vinyl chloride-based second seed; an initiator composition including a water-soluble initiator and an oil-soluble initiator; a reducing agent; and a vinyl chloride-based monomer, wherein a metal catalyst is not included in the composition, and a method for preparing a vinyl chloride-based polymer using the same.
Claims8
A composition for preparing a vinyl chloride-based polymer, the composition comprising:
- a vinyl chloride-based first seed;
- a vinyl chloride-based second seed;
- an initiator composition comprising a water-soluble initiator and an oil-soluble initiator;
- a reducing agent;
- and
- a vinyl chloride-based monomer,
- wherein the composition does not comprise a metal catalyst, and
- wherein an amount of the reducing agent is 60 to 100 ppm based on a weight of the vinyl chloride-based monomer.
