  • Patent number: 4112208
    Abstract: The invention relates to a process for the treatment of substantially amorphous polyolefins with peroxides at high temperatures to provide permanently tacky, low viscosity materials which have useful pressure-sensitive adhesive properties. These permanently tacky amorphous polyolefin homo- and copolymers, as well as blends of such amorphous polyolefins with crystalline polyolefins containing up to 20 weight percent crystalline polyolefin, are novel pressure-sensitive adhesives. These permanently tacky polymers are obtained, for example, by treating substantially amorphous polyolefins, such as amorphous polypropylene or amorphous propylene/1-butene copolymers, with peroxides at high temperatures.

  • Patent number: 4072812
    Abstract: This invention relates to single component, hot-melt, pressure-sensitive adhesives based on propylene/higher 1-olefin copolymers containing 40-60 mole % of more than one higher 1-olefin. Suitable comonomers include 1-hexene through 1-decene. These new adhesives can be readily applied to substrates such as tape by means of conventional hot-melt coating equipment and thereby eliminate the solvent pollution problems associated with the application of current solvent-based pressure-sensitive adhesives. Our hot-melt coated tapes generally have pressure-sensitive adhesive properties at least equivalent to those of solvent coated pressure-sensitive tapes.

  • Patent number: T100204
    Abstract: Disclosed is a primer coating composition for use between thermoplastic materials and metal. The primer composition comprises a polyester, at least half of the dibasic acid components of which are selected from terephthalic acid, isophthalic acid, 1,4-cyclohexanedicarboxylic acid or a mixture thereof. The polyester is either amorphous, or may contain some crystallinity to result in a melting point below about 175.degree. C. The heat of fusion of the polyester is less than about 10 calories per gram. The primer is especially useful in promoting adhesion between metal foil and cellulose acetate butyrate laminated thereto.
