  • Publication number: 20020183406
    Abstract: The present invention provides a polymer composition for film formation which provides a film having sufficient elongation and strength even on the surface of the film with sharp irregularities by rewetting with water after coating and drying. The polymer composition for film formation contains at least one component selected from the group consisting of an emulsion comprising a homopolymer of polyvinyl acetate or a copolymer of polyvinyl acetate with a monomer selected from acrylic ester, acrylic amide, acrylic acid, methacrylic acid, methacrylic ester, maleic acid, maleic anhydride, and fumaric acid, and an aqueous solution of sap, fruit liquid, honey, and saccharide.

  • Publication number: 20020169221
    Abstract: The disclosed process to obtain a modifier for cement systems comprises a synthesis of the modifier by a process of polymerization in a soft alkaline catalysis. This contributes to the formation of a product with a low molecular mass and viscosity. The concentration of the homogeneous aqueous solution is from 40-58% and the specific production of the process is Q=0.25 to 3.00 kg per hour in comparison with the specific production of the known prototype which is Q=0.03 to 0.04 kg per hour. One of the most important characteristics of the new process used to obtain the disclosed modifier is the fact that synthesis is achieved without external heat sources. Also, synthesis is achieved either by a periodic process or a continuous process.

  • Publication number: 20010008643
    Abstract: Conventional SBR does not have the soft and smooth chew characteristics needed in chewing gum base for soft chew applications. Conventional SBR typically also has undesirable odor and taste characteristics that have generally limited its use in chewing gum base formulations. However, there is a desire to use SBR in such applications because it is relatively inexpensive. The present invention also specifically discloses a process for synthesizing styrene-butadiene rubber that is particularly useful in manufacturing chewing gum base for soft chew applications which comprises copolymerizing about 1 phm to about 12 phm styrene and about 88 phm to about 99 phm of 1,3-butadiene in an aqueous emulsion, wherein said copolymerization is conducted at a temperature which is within the range of about 1° C. to about 20° C.

  • Patent number: 6248614
    Abstract: An electronic module having enhanced adhesion at the chip passivation and underfill interface is disclosed. The surface of the chip passivation is chemically modified to a sufficient depth such that the cured passivation is more reactive. The modified surface is treated with a polyamine preferably having a cyclic amine group extending from a preferably aliphatic backbone. During reflow of the solder joints of the electronic module by heating, the modified passivation reacts with the polyamine at the amine functionality. Following underfill of the electronic module with a polymeric material, preferably an epoxy resin, the polyamine on the surface of the passivation reacts with the underfill material during curing of the underfill material. The resulting electronic module is more robust since the amine acts as a chemical anchoring site for both the modified passivation and the underfill material.

  • Patent number: 5085697
    Abstract: A splendid tentative surface protective coating which is useful in treating a surface of a substance by soldering or plating and which is peeled off easily from the surface after the treating is formed by preparing a solventless or solvent free type screen ink based on essentially an ultraviolet ray-curable rubbery elastomer, applying a coating of the ink on the surface of the substrate by screen printing or thin film coating, and curing the coating of the ink by irradiation with an ultraviolet ray. The tentative surface protective coating can reproduce exactly a pattern of a mask or screen, have a high chemical resistance and heat resistance, even if it has a thin thickness of 30 .mu.m, and have no afraid of deformation caused by heat curing, whereby a precise and shortened surface treatment of the surface of the substance can be afforded. Also, working environment is improved, and air conditioning equipment can be dispensed with owing to an absence or diminishment of an organic solvent.

  • Patent number: 4609745
    Abstract: Disclosed are new zirconic acid esters which contain glycol ether moieties as the ester grouping, and which are chelated with one and up to a maximum of two moles of acetylacetone. The new compounds can also contain up to a maximum of two moles of ester groupings of low alkanols. The new partially chelated zirconic acid esters are characterized by good solubility in water, in which they do not decompose at room temperature. Accordingly, they can also be used in aqueous systems as crosslinking agents or reaction accelerators.
