    Abstract: A package is made by packing a compound of the formula (1) in a bag comprising a thermoplastic resin as a main component, wherein the film thickness of the bag is preferably from 50 to 200 ?m: wherein each of R1 and R2 is independently an alkyl group having 1 to 5 carbon atom(s); R3 is a hydrogen atom or an alkyl group having 1 to 3 carbon atom(s); and R4 is a hydrogen atom or a methyl group. The compound is taken out of the bag and is then added to a thermoplastic resin which may be the same as or different from the thermoplastic resin as the main component of the bag to obtain a composition; and the composition is formed into a thermoplastic resin film. In this regard, no paper chip arises even if the bag containing the above-described compound is roughly opened with a cutter or the like, and thus, occurrence of fish eye gels in the film can be suppressed when the film is formed of the composition comprising the thermoplastic resin and the above-described compound.

  • Patent number: 6958412
    Abstract: A method for synthesizing a pentafluorophenyl acrylate polymer includes bulk polymerizing a pentafluorophenyl acrylate monomer in the presence of a free radical initiator. The reactant mixture was subjected to an ultrasonication treatment, so that the mixing of the initiator and the monomer is enhanced; carried out the bulk polymerization at 25-99° C. for a period of time, and at 100-200° C. under a vacuum pressure for another period of time to complete the bulk polymerization, so that residue amounts of the initiator, unreacted monomer and oligomer of the monomer are reduced in the resulting reaction mixture.

  • Patent number: 6943194
    Abstract: A newly discovered antineoplastic compound denominated “phenstatin” is herein described as are synthetic methods for producing phenstatin and the active prodrug thereof. Phenstatin was converted to the sodium phosphate prodrug (3d) by a dibenzylphosphite phosphorylation and subsequent hydrogenolysis sequence 3b?3c?3d. Phenstatin (3b) was found to be a potent inhibitor of tubulin polymerization and the binding of colchicine to tubulin comparable to combretastatin A-4 (1b).
