ABSTRACT:
The present invention provides for an improved butyl rubber composition which exhibits improved adhesion to pre-treated polyester textile materials, while at the same time important physical properties of cured butyl rubber such as modulus, tensile strength and elongation are maintained or even enhanced. The vulcanizable composition of the invention is based on a blend of butyl rubber and minor amounts of a copolymer of ethylene with a lower alkyl acrylate or methacrylate, or a terpolymer of ethylene, a lower alkyl acrylate or methacrylate and acrylic or methacrylic acid. The composition of this invention exhibits improved adhesion to pre-treated polyester textile materials.
The invention also relates to laminates of the butyl rubber compositions of this invention with polyester textile materials such as yarns and woven fabrics.
