  • Patent number: 5952396
    Abstract: An elastomer has a modulus intermediate between that of a conventional rubber and a gel. The elastomer includes (a) between 20 and 45 parts by weight of a semicrystalline elastomer having between 1 and 15% crystallinity and (b) between 80 and 55 parts by weight of a compatible liquid elastomer having a number-average molecular weight of between 1,500 and 8,500. The elastomer's modulus is sufficiently high to enable it to be fabricated into handleable articles, but is sufficiently low so that it provides effective sealing of substrates it covers without the need for introducing a separate sealing material such as a mastic or adhesive.

  • Patent number: 5853874
    Abstract: A low melt viscosity hot melt pressure sensitive adhesive composition having enhanced tack properties is provided. The composition is based on an S-I-S block copolymer having polystyrene and polyisoprene block segments blended with a petroleum tackier resin which is the Friedel Crafts polymerization product of (i) a cracked petroleum feed containing C.sub.5 olefins and diolefins or a mixture of C.sub.5 and C.sub.6 olefins and dioelefins copolymerized with (ii) from about 5 to 15% by weight of a monovinyl aromatic monomer having 8 or 9 carbon atoms, e.g., styrene. The composition optionally also includes a polystyrene--polyisoprene diblock copolymer and a processing oil. The composition may be readily applied as solvent-free melt to various substrates using coating die technology because of its low melt viscosity at coating temperatures.
