摘要:
Polymers and compounds including a diphenylmethylene or a 9H-fluorene moiety; and sunscreen compositions including a mixture of a photoactive compound and any one of the foregoing derivatives are disclosed herein. Also disclosed are methods for stabilizing a sunscreen composition by the addition of one or more of the foregoing derivatives, methods of filtering out ultra-violet light from a substrate by the use of one or more such derivatives, and methods for terminating a polymerization reaction by the addition of derivatives of diphenylmethylene and/or 9H-fluorene. Synergistic combinations of the polymer with (1) diesters or polyesters of a naphthalene dicarboxylic acid, or (2) oxybenzone enhance the photostability of sunscreen compositions containing a photodegradable sunscreen active compound, such as avobenzone.
摘要:
A method is provided for synthesizing a polymer in a controlled fashion using a ring-opening metathesis polymerization (ROMP) reaction, wherein polymerization is carried out using a catalytically effective amount of an olefin metathesis catalyst and a bridged bicyclic or polycyclic olefin monomer that contains at least two heteroatoms directly or indirectly linked to each other. Preferred catalysts are Group 8 transition metal complexes, particularly complexes of Ru and Os. Such complexes include the ruthenium bisphosphine complex (Pcy3)2(Cl)2Ru=CHPh (1) and the ruthenium carbene complex (ImesH2)(Pcy3)(Cl)2Ru=CHPh (2). The invention also provides novel regioregular polymers synthesized using the aforementioned methodology, wherein the polymers may be saturated , unsaturated, protected, and/or telechelic. An examplary polymer is poly((vinyl alcohol)2-alt-methylene)(MVOH).
