Abstract: Described herein is methacrylate copolymer derived from: a (meth)acrylate monomer comprising a second terminal olefin group; an alkyl methacrylate monomer wherein the alkyl group comprises 1 to 4 carbon atoms; a mono(meth)acrylate monomer comprising a low-surface-energy group, wherein the low-surface-energy group comprises a perfluorinated alkyl group, a perfluorinated polyether group, or a silicone group; and a RAFT agent. Such copolymers can be used to make liquid compositions, which may then be used to generate tooling for nanoimprint or transfer lithography.

Abstract: Polymerizable compositions are provided, including a polymerizable component and a redox initiation system. The redox initiation system includes a transition metal complex that participates in a redox cycle; an oxidizing agent; and a photolabile reducing agent containing a benzophenone moiety. On exposure to actinic radiation, such as UV, the photolabile reducing agent photolyzes, releasing the reducing agent and initiating the redox-initiated polymerization of the polymerizable component. Also provided is a photolabile reducing agent.

Abstract: An optical ferrule assembly includes an optical ferrule including an attachment area, a light input surface and a light output surface; an optical fiber having a fiber end where the light input surface and the fiber end defines a gap therebetween substantially filled with an adhesive, such that light propagating along the optical fiber and having a peak intensity I1≥3 GW/m2, exits the fiber end and enters the optical ferrule through the light input surface after traversing the gap through the adhesive, and exits the optical ferrule through the light output surface. The exiting light has a first beam size, such that after at least 100 hours of aging of the optical ferrule assembly, any change in the first beam size due to a photodegradation of the adhesive is no more than about 10%. The adhesive can be prepared by photocuring an optical adhesive formulation.
