  • Patent number: 8906980
    Abstract: The present invention relates to a water-soluble polymer composition which comprises a water-soluble poly(meth)acrylic polymer and a gelation rate retarding agent, and a composition for forming a plaster layer of a skin patch which is obtainable by adding a polyvalent metal compound to the water-soluble polymer composition. When a polyvalent metal compound is added, the aforesaid water-soluble polymer composition shows an appropriate induction period before the start of the hardening of the gel. When the water-soluble polymer composition is used for forming a plaster layer of a skin patch, therefore, additive ingredients can be uniformly mixed and the procedure for coating to a support can be facilitated.

  • Publication number: 20100056718
    Abstract: In a first step, a diamine is reacted with a molar excess of a tetracarboxylic dianhydride in a solvent containing more than ? mole of water per mole of the tetracarboxylic dianhydride, whereby preparing a polyamic acid solution. Subsequently, in a second step, a diamine and/or a tetracarboxylic dianhydride are added to the polyamic acid solution obtained in the first step so that the molar amount of the diamine component is substantially equal to the molar amount of the tetracarboxylic acid component, and then the diamine and the tetracarboxylic dianhydride are reacted, whereby preparing a polyamic acid solution. By this process, a polyamic acid solution having a high concentration and a low viscosity may be reproducibly and reliably produced, while controlling the molecular weight of the polyamic acid to a predetermined low level.

  • Patent number: 7598313
    Abstract: Polymer capsules from amphiphilic graft copolymers comprising reactive, hydrophobic polyolefin backbones, and hydrophilic poly(ethylene glycol) (PEG) grafts are produced by self-assembly of the polymers at the oil-water interface, and crosslinking the assembly with bis-cyclooctene PEG derivatives in conjunction with ring-open metathesis polymerization catalysts. The use of the graft copolymer architecture in capsule synthesis provides significant opportunities to tune both the surface properties, in terms of recognition, and the membrane properties, in terms of mechanical strength, encapsulation, and release.

    Abstract: The invention relates to a method for production of polyester resins containing nanodisperse nanoscale additives as binder for powder paints, whereby firstly at least one precursor compound for nanoscale solid particles to be formed is added to the reaction starting materials during the resin synthesis and distributed in the reaction starting materials. The precursor compound(s) which may be reacted at a temperature between 30? and 260° C., preferably between 80° and 250° C., are reacted to give the desired nanoscale solid particles under the effect of a reaction temperature in the range between 30? and 260° C., preferably between 80? and 250° C., the nanoscale solid particles thus formed being nanodispersedly distributed in the polyester resin.
