With a total of 2 patents, Bartel's work has implications for various applications in the industry.
Latest Patents
Bartel's latest patents include a mixture yielding thermally stable photo-cross-linkable layers and foils. This invention provides mixtures based on resins containing allyl groups that are solid at room temperature. These mixtures are useful for preparing thermally stable, photo-crosslinkable layers and foils. The invention comprises triallylcyanurate prepolymers and/or triallylcyanurate precopolymers combined with compounds containing allyloxy and/or allylester groups, as well as compounds with at least one N-maleimide group. The N-maleimide C=C bonds are preferably bonded to hydrogen, enhancing the stability of the materials.
Another significant patent is a method for the preparation of relief structures. This method involves novel cyclic monomers that leave two functional groups capable of undergoing condensation reactions to form amide, urea, or urethane linkages. These monomers are condensed with cyclic comonomers to create a soluble, substantially-linear condensation pre-polymer. The prepolymer solution is applied to a substrate, evaporated to form a film or foil, and then exposed to a pattern. The resulting relief structures are characterized by sharp edges, good mechanical and chemical properties, and excellent insulating properties, making them suitable for miniaturized insulating layers.
