METHOD OF PREPARING VINYL CHLORIDE RESIN HAVING HIGH IMPACT STRENGTH AND LOW DIE SWELL

摘要

A method of preparing vinyl chloride resin is provided. In the method, a first vinyl chloride monomer is mixed with a first initiator to prepare a seed polymer particle and a second vinyl chloride monomer and a second initiator are added to the polymerized seed polymer particle. An organic siloxane polymer is added to the first monomer and/or second monomer of Formula (1), wherein R1 is hydrocarbon having 1 to 12 carbon atoms and substituted with a group selected from the group consisting of hydrogen, alkyl, haloalkyl, aryl, haloaryl, aralkyl, polyether, imino, epoxy and vinyl; R2 is saturated hydrocarbon having 1 to 12 carbon atoms; and n is an integer of 10 to 12,000.
