Provided are methods of evaluating deodorizing ability of a superabsorbent polymer and a product including the same. According to the methods of evaluating deodorizing ability of the present invention, deodorizing ability of the superabsorbent polymer and the product including the same may be evaluated by measuring changes in the concentration of ammonia naturally generated in a wet state which is made close to the actual use environment. Accordingly, the deodorizing ability of the superabsorbent polymer and the product including the same may be evaluated more accurately and efficiently.

Disclosed are a water-dispersible halogen-capping polyalkylacrylate, a vinyl chloride-based block copolymer and a method for preparing the same. By using the water-dispersible halogen-capping polyalkylacrylate derivative as a chain transfer agent for polymerization of a vinyl chloride-based monomer, it is possible to obtain effects such as reduction of coagulation of particles and adhesion of particles to a reactor wall, improvement in reaction efficiency and polydispersity index, and prevention of yellowing.

Disclosed are a bulk PVC composition and a bulk PVC polymerization method using the same. According to the present invention, a bulk PVC composition that may effectively prevent generation of fine particles and scale (adhering to a reactor wall) during bulk polymerization and may be prepared without a post-treatment process of an antistatic agent added to easily isolate fine particles after bulk PVC polymerization, and a method and apparatus for polymerizing the same may be provided.
