Publication number: 20140227212Abstract: A soluble UVA and/or UVB absorbing chromophore-comprising polymer useful for preparation of a sunscreen lotion has a multiplicity of repeating units where one or more of the repeating units includes at least one UVA and/or UVB absorbing chromophore. The repeating units are those formed from the ring-opening metathesis polymerization (ROMP) of a strained cycloakene, cycloalkadiene, bicycloalkene, or bicycloalkadiene, or where one or more sp3 hybridized carbons of the strained cycloakene, cycloalkadiene, bicycloalkene, or bicycloalkadiene is replaced with a heteroatom. The UVA and/or UVB absorbing chromophore-comprising polymer can be formed from a UVA and/or UVB absorbing chromophore-comprising monomer, which can be homopolymerized or copolymerized by ROMP. Alternately, the UVA and/or UVB absorbing chromophore-comprising polymer can be formed by polymerization of monomers that can subsequently be substituted with UVA and/or UVB absorbing chromophores.Type: ApplicationFiled: September 10, 2012Publication date: August 14, 2014Applicant: UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Kenneth B.

Patent number: 7754842Abstract: Acyclic diene metathesis (ADMET) has been utilized in the synthesis of carbosilane and carbosiloxane polymers bearing a latent reactive methoxy-functional group on each repeat unit. The polymerization results in a linear thermoplastic polymer. The latent reactive methoxy groups remain inert during polymerization; however, exposure to moisture triggers hydrolysis and the formation of a chemically cross-linked thermoset. The thermoset's properties can be modified by varying the ratio of carbosilane and carbosiloxane repeat units in the final material. Also, increasing cross-link density by using cross-linkable chain-end groups and increasing the run length of the soft phase, maximizing phase separation and elasticity, allows for the synthesis of elastic thermosets exhibiting good tensile strength. Adding a trifunctional ADMET active chain-end cross-linker to the system improved the mechanical behavior of the resulting polymer.Type: GrantFiled: July 21, 2008Date of Patent: July 13, 2010Assignee: University of Florida Research Foundation, Inc.Inventors: Kenneth B. Wagener, John C. Sworen, Hector F. Zuluaga, Piotr Matloka
