PROCESS FOR PREPARING A DISPERSION AND FOR PREPARING POLYMER PARTICLES |
摘要 |
<p>PCT No. PCT/NO92/00123 Sec. 371 Date Apr. 22, 1994 Sec. 102(e) Date Apr. 22, 1994 PCT Filed Jul. 15, 1992 PCT Pub. No. WO93/02112 PCT Pub. Date Feb. 4, 1993Process for producing a dispersion, wherein dispersed slightly crosslinked polyvinyl seed particles are swollen with an ionizing liquid, said seed particles containing covalently linked ionizable groups causing a swelling of the seed particles by the ionizing liquid to form a dispersion of droplets, wherein the resulting droplets after the swelling have a volume which is at least five times that of the seed particles. Said ionizing liquid may be or contain a polymerizable monomer or be charged with such a monomer. Polymerization of the monomers is effected in the droplets during or after the swelling, to form polymer particles.</p> |
