Abstract

Ny filmbeleggdispersjon som kan oppnås ved polymerisering av følgende monomerer i vann: akrylsyre eller en ester derav i området 40 til 80 vekt-%; metakrylsyre eller en ester derav i området 20 til 60 vekt-% og et polymeriserbart overflateaktivt middel i området 0,01 til 9 vekt-%. Dispersjonen er egnet for belegning av farmasøytiske formuleringer for oppnåelse av regulert frigivning av den aktive bestanddelen.
