MICROFOAM BEADS AND METHOD FOR THEIR PRODUCTION. |
| abstract |
Core-shell microfoam beads have a shell obtd. by crosslinking a polyamine (I) and NCO-contg. carbodiimide (II) and a core (partly) filled with a polymeric NCO-contg. carbodiimide (III) or its reaction prod. with a polyamine (IV). The beads are self-supporting and hydrophilic. The shell is pref. wrinkled and contains polyurea and polyguanidine The beads have a maxdia. of 300 microns. The beads are produced by dissolving (III) in at least 20 (wt. = pts. org. solvent (pref. CHCl3), emulsifying the soln. in aq. phase, crosslinking (III) with (I), removing the solvent and drying if necessary. The beads may be charged with a suitable substance. |
