Polymer composition for controlled release of active ingredients in response to pH, and a process of preparing the same |
| abstract |
The present invention provides a polymer for the controlled release of a pendent chain linked active ingredient, and a process for the preparation of such a polymer for the controlled release of an active ingredient in response to pH. The process involves selecting a vinyl monomer to which the active ingredient molecule is covalently linked through a pendent group, and selecting monomers bearing catalytic groups. The active ingredient-bearing monomer and the catalytic group-containing monomer are brought in juxtaposition either by complexation or molecular imprinting, and then polymerized with a hydrophilic monomer and crosslinker under an inert atmosphere with a suitable polymerization initiator. |
