Initiator suspension, their preparation and use |
摘要 |
An initiator suspension for use in the suspension polymerization of ethylenically unsaturated monomers is prepared by (a) heating the initiator to its melting point; (b) finely dividing the initiator in water while it is in a molten state; and (c) rapidly cooling so that the initiator is in a molten state for a period of time which is less than about 5 minutes. The initiator suspension has very small particles and a narrow particle size distribution whereby at least 50% by weight of the particles are smaller than 5 mu m and at least 90% by weight of the particles are smaller than 10 mu m.
