Abstract

1415236 Chlorinating PVC POZZI FERRANDINA SpA 14 May 1973 [24 May 1972] 22927/73 Heading C3P Granular PVC is chlorinated in a fluidized bed in the presence of a light source and in the presence of a pigment as used in the subsequent compounding in powder or granular form. The pigment, e.g. carbon black or titanium dioxide is added in an amount of 0À001 per hour up to the maximum permissible in the subsequent compounding. Lower fluidization gas speeds may be used and the product is more homogeneously chlorinated than in the absence of pigment.
