    Abstract: A latent material having various controlled shrinkage tensions and patterns and a method of making the same. The materials include polymer materials that are capable of absorbing microwave energy. Different degrees of shrinkage of the material may be controlled to create different tensions in the material. Additionally, various stereo and three-dimensional patterns may be generated on the material. These materials may be used in the formation of personal care articles. The materials are made by incorporating a polymer material onto the film, wherein the polymer material is capable of turning microwave energy into heat. Upon exposure to microwave radiation, the heat will cause the latent material to shrink. The use of different types and amounts of polymer materials will result in a latent material having different tensions and patterns.

One method comprises treating a medium suspected of containing an analyte under conditions such that the analyte, if present, causes a photosensitizer and a chemiluminescent compound to come into close proximity. The photosensitizer generates singlet oxygen and activates the chemiluminescent compound when it is in close proximity. The activated chemiluminescent compound subsequently produces light. The amount of light produced is related to the amount of analyte in the medium. Preferably, at least one of the photosensitizer and chemiluminescent compound is associated with a surface which is usually a suspendible particle, and a specific binding pair member is bound thereto.

A mixture is prepared of (1) a monomer selected from the group consisting of vinyl chloride, vinylidene chloride, and mixtures thereof with up to about 20 wt % of a comonomer, (2) supercritical carbon dioxide, subcritical carbon dioxide, or liquid carbon dioxide in a weight ratio to the monomer of about 0.5 to about 5; and (3) about 0.1 to about 1 phr of a free radical initiator that is soluble in said supercritical carbon dioxide or a solution of said a free radical initiator in a solvent that is miscible with the carbon dioxide. The mixture is heated to a temperature of about 40 to about 70° C. to polymerize the monomer.

  • Patent number: 6175037
    Abstract: An improved process for preparing acrylate esters, methacrylate esters, polyester acrylates or polyester methacrylates by reacting acrylic or methacrylic acid with a monohydroxy containing compound or a polyhydroxy containing compound in the presence of a catalyst and polymerization inhibitor in a reaction vessel, in the presence or absence of a solvent, under microwave energy as a heating source. Advantages of using microwave energy in place of conventional thermal heating include higher temperatures coupled with shorter residence times, reduced production costs, increased capacity, lower energy costs, effective use of raw materials, and solventless processing which is environmentally friendly.

  • Patent number: 6099679
    Abstract: Methods for gluing a pair of surfaces are disclosed including preparing a glue from a polymer in the form of a powder, the glue having a melting temperature of up to about 100.degree. C. and being curable by electromagnetic radiation, applying the powder in a dry state to at least one of the two surfaces, heating a region proximate to at least one of the surfaces whereby the powder melts but does not cure, subjecting that surface to electromagnetic radiation to initiate curing of the powder, and joining the two surfaces together prior to completion of curing whereby the two surfaces adhere to each other by means of the tackiness of the glue and are maintained together by the subsequently cured glue. Apparatus for gluing the two surfaces together are also discussed, as are glue compositions for use therein.
