Abstract

1416004 Polymer particles containing magnetic material COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION and ICI AUSTRALIA Ltd 15 Jan 1974 [31 Jan 1973] 01843/74 Headings C3F C3P and C3R Particles of narrow size distribution and comprising 30-90% (by weight of the composition) of magnetic particles in a matrix of a linear polymeric material are produced by (a) forming liquid droplets of the composition (in melt or solution. form), (b) solidifying the droplets, (c) separating the particles of the desired size range, (d) reconverting remaining particles to a liquid form and (e) recycling these to step (a). In examples particles of Fe 3 O 4 are mixed with an acetone solution of partially hydrolysed vinyl chloride-vinyl acetate copolymer, or ethylcellulose, or phenol-formaldehyde novolac, together with unwanted size particles from earlier preparations, the mixture dispersed in paraffin oil containing a surfactant, removing the acetone by means of a current of air while warming to 50‹ C. and separating the resultant solid particles from the paraffin. The products are magnetized and used as filter aids.
