Abstract: The present invention relates to a process for producing polymeric structures that have activated surfaces. The process proved to be simple, quick, with high production capacity and low operating costs. The process occurs by depositing a polymer solution, which is assisted by a high electric field, on a conductive liquid surface to produce particles and/or filaments that have an activated surface. More particularly, the process of the present invention has the ability to produce particles and/or filaments that have chemically activated surfaces, in a single process.

Abstract: Fibers can be formed from monomers derived from a biorenewable source. In an embodiment, a fiber forming composition that includes a monomer or mixture of monomers with at least one monomer being derived from a biorenewable source in placed in a fiber producing device. At least a portion of the fiber forming composition is ejected through an opening of the fiber forming device. The ejected fiber forming composition is subjected to light at wavelengths sufficient to activate a reaction which causes solidification of the fiber as the fibers are ejected from the fiber producing device.
