Use of this composition promotes tanning of the human skin and increases photoprotection from ultraviolet radiation.
专利号:US-5629394-A 优先权日:1992-12-17 标 题 :Direct synthesis by living cationic polymerization of nitrogen-containing polymers 发明人:CHERADAME HERVE M; CHEN FRANK J; STANAT JON E R; NGUYEN HUNG A; TABAR BEHROOZ R 权利人:EXXON CHEMICAL PATENTS INC 摘要:A method is provided for the direct synthesis by living cationic polymerization of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino, cyanato, thiocyanato or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or a tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

The copolymer beads have a first repeating motif, a second repeating motif having a substituted styrene with an ester functional group or an amide with a terminal amine or hydroxyl functional group, and a crosslinking agent having a divinyl compound. The copolymer beads are capable of expanding substantially uniformly in polar and non-polar solvents.

专利号:US-9314021-B2 优先权日:2004-11-03 标题 :Formulations containing insect repellent compounds 发明人:SCIALDONE MARK A 权利人:DU PONT 摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
