摘要： A process for the homo- or co-polymerisation of vinyl chloride monomer in aqueous miniemulsion is disclosed, comprising forming a micro suspension-like system by the chemical interaction of anion emulsifiers and linear organic monoalcohols, preferably ranging between C₁₆ and C₁₈ in hydrocarbon chain length, without the use of a mechanical homogeniser, using a thermostable organic peroxide slightly soluble in water as a radical source, whose half life is preferably more than 50 hours at the reaction temperature, which is activated by the addition of a reducing activator in the presence of a metal salt as a catalyst, preferably copper or iron. The reaction rate can be controlled by varying the rate of addition of the activator. The levels of build up on the reactor walls are greatly reduced and substantially eliminated.
