Zusammenfassung: | Disclosed is a process for producing an actives-comprising polymeric network by mixing polymerizable oligomers and actives and also, optionally, further monomers and/or auxiliaries, followed by thermal or photochemical polymerization of the mixture, wherein the polymerizable mixture comprises the following components: (A) 19.9 to 99.8 percent by weight of at least one oligomer containing mono(meth)acrylate groups and having an average molar mass of 350 to 5000 grams per molecule, selected from the group of epoxy (meth)acrylates, polyester (meth)acrylates, urethane (meth)acrylates or polyether (meth)acrylates, the arithmetic average of the number of (meth)acrylate groups per oligomer molecule being 2.1 to 5; (B) 0 to 49.8 percent by weight of at least one monomer containing olefinic groups and having a molar mass of less than 350 grams per molecule; (C) 0.1 to 8 percent by weight of at least one polymerization initiator which is soluble in the photopolymerizable mixture; (D) 0.1 to 80 percent by weight of at least one active which is dispersible or soluble in the photopolymerizable mixture; and (E) 0 to 20 percent by weight of further auxiliaries and/or additives. Further disclosed is an actives-comprising polymeric network obtainable by said process, and the use of said actives-comprising polymeric network for protecting industrial materials, films, paints and dispersions, crops, and for controlling plant growth. |
