A potentially hydrophilic resin composition comprises, in a liquid medium, the potentially hydrophilic and an adhesive component or film-forming component. A recycling method is provided for an article with a coating applied on a surface thereof. According to the recycling method, the coating on the surface of the article is formed with the potentially hydrophilic resin composition, and subsequent to use of the article, the article is treated with alkaline water to saponify methyl acrylate in the coating such that the coating is caused to swell, and the coating so swollen is removed from the article.

  • Patent number: 6194519
    Abstract: The present invention relates to low-cost, efficiently-manufactured, polymer-based products useful as roofing shingles and similar products. The inventive shingles are weatherproof, inexpensive to manufacture and durable, particularly as contrasted with conventional shingles in areas of the country subject to hail damage. The invention also includes a method of making such shingle products. In a preferred embodiment, products of this invention use rubber material as the polymer base in combination with specific types of polyolefins. The rubber material can be most efficiently provided by the use of crumb rubber particles from spent automobile tires and other recycled rubber debris which are readily available and of very low cost. The products will have an average life far greater than that of current commercial roofing shingles, which are made using fiberglass or asphalt.

  • Patent number: 6136914
    Abstract: Novel solid supported anionic polymerization initiators that are multiply metalated with Group IA alkali metal atoms are provided and employed to produce extremely high molecular weight branched diene polymers. The initiators are prepared by metalating a particle comprising a thermoplastic polymer or a cured elastomer in the presence of a polar coordinator. The polymers obtained by anionic polymerization employing the initiators are multiply branched, with a polymer chain covalently attached to the particle at virtually every metalation site. The macro-branched polymers exhibit desirable properties, such as an extremely high molecular weight, a controlled molecular weight distribution, T.sub.g and vinyl content, and the ability to readily absorb hydrocarbon solvents and oils. The polymers are easily compounded to form vulcanizable elastomeric compounds and articles that have excellent resistance to wear and tear and exhibit reduced hysteresis properties.

  • Patent number: 5604290
    Abstract: A self-crosslinking composition contains: (a) an oil having an unsaturated fatty acid or an ester of an unsaturated fatty acid as one of its components, (b) a drier, and (c) a polymer or an elastomer that is capable of crosslinking in the absence of a peroxide. A forming (such as a floor tile, a linoleum long floor material, a wall material and a water-proof sheet) may be manufactured by forming and curing the self crosslinking composition and then adding a filler. Since the self-crosslinking composition is capable of crosslinking without using peroxide, the crosslinking reaction is easily conducted without using special equipment to reject air. The composition has a number of advantages over crosslinking methods that use peroxide, including decreased scorch generation, decreased permanent compressive strain, and superior heat resistance and anti-aging resistance. The composition is free from pollution of sulfur and metal and generates no harmful gas during waste incineration.
