  • Patent number: 4332703
    Abstract: Plastic bituminous compositions comprising(a) 100-30 % w of a mixture of1. 45-99.8 % w of a bituminous component having a penetration of less than 800 (0.1 mm) at 25.degree. C.,2. 0.1-30 %w of a lithium salt of a C.sub.10 -C.sub.40 (hydroxy) fatty acid, and3. 0.1-25 %w of a thermoplastic polymer, and(b) 0-70 %w of a filler having excellent self-adhesive properties even when applied on wet or wetted surfaces. They are cold applicable and shear-stable.
    Type: Grant

  • Patent number: T964011
    Abstract: article provided with a pressure-sensitive adhesive layer composition, which composition is characterized by improved flow resistance at high temperatures (e.g. at 90.degree. C), and which comprises 50-97 parts by weight of a bituminous component dispersed in an extender oil, 3 to 50 parts by weight of at least one thermoplastic polymer, which is preferably a block polymer having the general structure:A--B--(B-A)nwhere A is a monoalkenyl arene block, B is a conjugated diene block, and n is an integer from 1-15, and 5 to 50% by weight (based on the combined weight of the bituminous component and the thermoplastic polymer) of a carbon black having an oil absorptivity of above 80 milliliters per 100 grams. Such articles usually possesses good low temperature flexibility, tack and adhesive strength.
