Abstract
Disclosed herein are polymeric molds that can be used to make molded articles. The polymeric molds are made from cyclic olefin polymers that may be formed by ring opening metathesis polymerization (ROMP) of a polycyclic monomer having two or more reactive double bonds and a cyclic monomer comprising one reactive double bond. Fluorinated monomers may be used. The polymeric molds may be structured molds in that they have at least one microstructured feature having a dimension of less than about 2 mm, or less than about 500 um. The polymeric molds may also have a plurality of such microstructured features. Also disclosed herein are methods of making the polymeric molds, methods of making molded articles therefrom, and the molded articles.
Claims9
A polymeric mold comprising a polymer formed by ring opening metathesis polymerization of:
- a polycyclic monomer having two or more reactive double bonds, and
- a cyclic monomer comprising a reactive double bond, the cyclic monomer comprising a fluorinated cyclic monomer comprising:
- wherein R2 is selected from the group consisting of:
- a covalent bond, an alkyl group, an aromatic group, an ester, an amide, an ether, and a sulfonamide:
- and Rf is a fluorine-containing group, including a monovalent perfluoroalkyl-containing group or a perfluorooxyalkyl-containing group.
