POROUS POLYMERIC BEADS FOR THE DELIVERY OF AN ACTIVE INGREDIENT |
摘要 |
<p>Delivery vehicles comprised of a polymeric bead having a network of pores with an active ingredient held within the network are provided for use in a method to provide controlled release of the active ingredient. The network of pores is substantially non-collapsible upon removal of the active ingredient and the delivery vehicles are polymerized by a process in which the active ingredient also comprises the porogen during formation of the network of pores.</p> |
