Abstract: A composition comprising a polymer of isobutylene with a minimum content of 80 per cent of isobutylene, preferably of molecular weight 30,000 to 300,000, and at least 30 per cent of a silicate filler based on the total mixture is used as a sealing profile for expansion joints of structures, particularly of concrete or reinforced concrete. Copolymers of isobutylene with 0.5 to 20 per cent of butadiene, isoprene, pentadiene - 1,3, 1,3 - trimethylbutadiene - 1,3, hexadiene-1,3, 2-chlorobutadiene, cyclopentadiene, styrene, a -methyl styrene, vinyl ethers and dimethyl and diethyl fumarates, may be used. Suitable fillers are dispersed silicic acid, silica gel, siliceous chalk, kieselguhr, infusorial earth, feldspar, kaolin, bole, bentonite, asbestos, steatite, talc, cement, glass powder and shale or pumice powders. Activated carbon, zinc oxide, asphalt, stearic acid, mineral waxes, polyethylene, or polyisobutylene of molecular weight 10,000 or 15,000 may also be present in 15 to 25 per cent by weight. The profiles may be extruded or rolled and afterwards vulcanized with the aid of sulphur, mercaptobenzothiazole and tetramethylthiuram disulphide.
