  • Patent number: 4889884
    Abstract: This invention presents a series of synthetic based cold seal adhesives which are capable of forming a strong bonds at room temperature, yet which may be reeled up without blocking and stored for extended periods of time. Such adhesives can be used in place of the natural rubber based cold seal adhesives currently used, and thus, can be employed in any packaging application where cold seal properties are desirable.

  • Patent number: 4833189
    Abstract: Composite resin particles each comprising a particulate crosslinked polymer to which a number of substantially linear, metal-containing polymer chains are chemically bonded. The invention also provide methods for the preparation of said composite resin particles. The present composite resin particles have self-film forming properties, can give a stable dispersion in an organic solvent or a resinous varnish and are specifically useful in paint industries. The particles are further characterized by having the desired properties of the metal element contained therein, as, for example, self-catalytic function in crosslinking, excellent biological activities and the like.

  • Patent number: 4731417
    Abstract: Disclosed is a multicomponent resin composition which is essentially a blend of three polymers, each of which may be a copolymer, and undergoes a change in light transmittance and color with temperature. The first and second polymers are chosen in combination such that a blend thereof exhibits a phase diagram in which a lower critical solution temperature appears, and the third polymer is one which has mutual solubility, at least partially, with either or both of the first and second polymers. For example, polymethyl methacrylate and a copolymer of vinylidene fluoride and hexafluoroacetone, as the first and second polymers, and polyvinyl acetate are blended together. The phase separation temperature or coloring temperature of the multicomponent resin composition depends on the amount of the third polymer, and opacifying and coloring of the resin composition caused by heating become irreversible by cooling when the amount of the third polymer is sufficient.

  • Patent number: 4384032
    Abstract: A fluid transmitting polyolefin foam having a special open-cell cellular structure as compared with the conventional polyolefin foams having all cells closed is disclosed. Such a novel fluid transmitting polyolefin foam is produced by mixing a polyolefin with a polymer other than a polyolefin, said polyolefin and/or said polymer other than a polyolefin having a blowing agent incorporated therein and/or adhered thereto and subjecting the resulting mixture to extrusion moulding. The present fluid transmitting polyolefin foam has a wide variety of uses, for example, as a synthetic leather, synthetic filter cloth, separator of storage battery, synthetic paper, package, etc.
