1. one kind is passed through polymerizable oligomer and active substance and optional other monomer and/or auxiliary agent mixing, make mixture heat or photochemical polymerization then and prepare the method for the polymer network that contains active substance, wherein polymerizable mixture comprises following component:

  • (A) at least a list (methyl) acrylate group and the average molar mass M of containing of 19.9-99.8 weight % nOligomer for 350-5000g/mol, described oligomer is selected from epoxy (methyl) acrylate, polyester (methyl) acrylate, carbamate (methyl) acrylate or polyethers (methyl) acrylate, wherein the arithmetic mean of (methyl) acrylate group of each oligomer molecules is 2.1-5 (B) at least a ethylenic group and the molal weight M of containing of 0-49.8 weight % nLess than the monomer of 350g/mol, (C) polymerization initiator at least a mixture that dissolves in photopolymerization of 0.1-8 weight %,(D) 0.1-80 weight % at least a disperse or be dissolved in the mixture of photopolymerization active substance and(E) other auxiliary agent of 0-20 weight % and/or additive,Wherein said amount is in each case all based on the total amount of all components of polymerizable mixture, and the amount of all used components (A)-(E) is 100%.
