Abstract
Thermally insensitive adhesives having good adhesion to cementitious substrates and having good low temperature flexural strengths, which consists essentially of the reaction product of asphalt flux, a polymerizable vinyl aromatic monomer, a non-depolymerized rubber, a depolymerized rubber and a terpene resin are provided. These adhesives are outstandingly adapted for use as the adhesives for preformed membranes of the type which comprise an asphaltic coated fibrous reinforcement material having an asphalt based pressure sensitive adhesive on one side thereof.
