Novel process for the preparation of a stable, pumpable aqueous suspension of an organic peroxide or mixed organic peroxides, and also novel suspension itself. Such suspensions are suitable for the initiation of polymerisation/ copolymerisation of ethylenically unsaturated monomers in particular vinyl chloride, to form respectively general purpose polymers and polyvinyl chloride that meets the volume resistivity specifications required of electrical cable sheathing materials. The said process is characterised in that the aqueous suspension is made to contain one or more organic peroxides, at least one protective colloid and a surfactant (as herein defined) selected from the group consisting of fatty acid esters of polyhydric alcohols, and alkanolamides. |
