Abstract: An adhesive for bonding polyamides to rubber comprises a mixture of 80 to 40% (all percentages by weight) of a 10 to 20% aqueous solution of a resorcinol-formaldehyde condensate at a molar ratio of formaldehyde to resorcinol of from 1:2 to 2:1 and p 20 to 60% of a 20 to 60% aqueous dispersion of a copolymer derived from 30 to 70% butadiene, 67 to 20% styrene and 3 to 10% of a N-vinyl-imidazole (including substituted derivatives) or a N-vinylcarbazole (including substituted derivatives). For use with a polyamide fabric, the fabric may be soaked or impregnated with the adhesive mixture, allowed to dry and then pressed on to the rubber at 150 DEG C. with a pressure of about 20 kg/cm2. If foils of polyamides are used, they are preferably pre-treated with an aqueous solution of a resorcinol-formaldehyde condensate. Example (1) describes a conventional preparation of a butadiene-styrene-N vinylimidazole copolymer and also the preparation of a suitable resorcinol-formaldehyde condensate. A finely meshed fabric of polyamide fibres is bonded with a mixture of these two components on to an unvulcanised natural rubber. In another example N-vinyl-benzimidazole replaces N-vinylimidazole.

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.
