  • Publication number: 20080274304
    Abstract: The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention.

  • Publication number: 20080236443
    Abstract: Embodiments relate to a relatively rapid transesterification process including transesterifying condensation polymers such as polyethylene terephthalate (PET), or other polyesters used in commerce, with a modifying monomer mix containing other monomers to manufacture new polymers containing the pre-condensed moieties. The process preferably only involves transesterification as a reaction mechanism. The process preferably produces a rapid buildup of molecular weight and/or polymer uniformity by the high temperature transesterification of the condensation polymer with the modifying monomer mixture. The process can be performed in any suitable vessel including an extrusion line, and it has the advantage of greatly reduced cycle times over currently used condensation polymer utilization processes such as the recycling of PET into other materials.

  • Patent number: 6930139
    Abstract: Coatings for agricultural grade fertilizer particles and industrial grade ammonium nitrate are provided which when applied to particles form a protective film which acts as a barrier to inhibit or prevent hydrocarbon infiltration of the fertilizer particle pores and also to physically separate the fertilizer particles and hydrocarbon materials. In so doing, the coating greatly reduces the efficacy of the fertilizer particles as an oxidizing agent for use in incendiary devices, thereby deterring or preventing the use of agricultural grade fertilizers or industrial grade ammonium nitrate in creating weapons of terror.

  • Patent number: 6852778
    Abstract: Anaerobically curable compositions comprising: (a) a polymerizable monomer having a functional group represented by the general formula: H2C=C(R)? (wherein R is a hydrogen atom or a methyl group) at a terminal of its molecule; (b) an organic peroxide; (c) o-benzoic sulfimide; and (d) a salt selected from the group consisting of sodium salts, potassium salts and calcium salts of weakly acidic substances, have a high curing rate and high bonding strength despite of having high storage stability. In particular, the composition can rapidly bond even adherends such as inactive metals and plastics, with which conventional anaerobically curable compositions are hardly cured.
