Methylmethacrylate vinylidene chloride

In this paper we would like to describe a new design, based on gas chromatographic analysis of the monomer mixture, for production of constant composition copolymers and its application to emulsion copolymerization. This design was already shortly described and applied to solution copolymerization (3) of methylmethacrylate and vinylidene chloride. Since then, the apparatus was made more simple, more reliable and more accurate. It is actually monitored by an analogic computering system which keeps the ratio of the monomers constant by controlling the addition of one of them. The process based on it can be called corrected batch process because the initial value of this ratio is kept up to the end.

The addition of HI onto vinyl monomers CH2=CR r has successfully led to the formation of the corresponding mono-addua CH3CR R I. For instance, this was applied to styrene (Sty), methylmethacrylate (MMA), ethyl acrylate (EA), vinyl acetate (VAc), vinyl chloride (VC), and vinylidene fluoride (VDF). One typical reaction is given in Scheme 2. ...
