Poly(2‐alkyl‐2‐oxazoline)s having an acrylate group at both chain ends were synthesized by terminating living bifunctional poly(2‐methyl‐2‐oxazoline) or poly(2‐ethyl‐2‐oxazoline) with acrylic acid. These macromonomers have been polymerized to the corresponding polyoxazoline networks. Thermal as well as UV‐initiated free radical polymerization were applied and the influence of the polymerization conditions and molecular weight of the prepolymer used on the properties of the networks were investigated. Both methods of polymerization produced high fractions of soluble material, probably due to the low concentration of the acrylate end groups.
