A process for preparing a copolymer containing combined vinyl chloride and ethylene in which vinyl chloride and ethylene are copolymerized batchwise in the presence of a free radical catalyst, the improvement which comprises dissolving a major portion of gaseous ethylene monomer in liquid vinyl chloride monomer, and carrying out the polymerization reaction by maintaining the reaction to this process, droplets of liquid vinyl chloride monomer (vcm), containing oil-soluble initiator(s), are dispersed in the continuous aqueous phase by a combi- nation of stirring and the use of suspending agents (stabilizers).
Abstract: world-wide consumption of pvc [poly(vinyl chloride)] has increased dramatically in the past few years. it has now exceeded 8 billion lbs annually. the production of vcm (vinyl chloride monomer) has also been expanded to meet the pvc demand. future trends chapter 1: introduction to polyvinyl chloride polyvinyl chloride (pvc) was first manufactured in germany in 1931 as a robust and lightweight new plastic. this breakthrough material was brought about to substitute for metals, glass, wood, natural fibers, papers and fabrics. over 30 million tons of pvc is used around the globe today, both in industrialized and developing countries, …

Uses of vinyl chloride (monomer) include the manufacture of chlorinated solvents (primarily 10000 tonnes per year of 1,1,1-trichloroethane) and the production of ethylene diamine for the manufacture of resins (who, 1999; european commission, 2003). vinyl chloride has been used in the past as a refrigerant, as an extraction solvent for heat-sensitive materials, in the production of chlo vinyl chloride monomer, or vcm, is the building block of pvc. most manufacturing of pvc around the world uses natural gas or petroleum as the “feedstock” or …
In general, when styrene monomer or vinyl chloride monomer is used to create a polymer, the potential for a small amount of residual monomer is present. process controls and robust engineering can limit the amount of a process for preparing a copolymer containing combined vinyl chloride and ethylene in which vinyl chloride and ethylene are copolymerized batchwise in the presence of a free radical catalyst, the improvement which comprises dissolving a major portion of gaseous ethylene monomer in liquid vinyl chloride monomer, and carrying out the polymerization reaction by maintaining the reaction
