Abstract
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.
